vlookup formula

Hi, I have the following 2 formulae and i have been desperately trying to
make them work but the dont!

I am looking up the value of column D in 1 worksheet to look across 10
different sheets (which are all named) and then return the results as "1,0"
when done into another sheet. So i am just looking up names from column D of
sheet"names" and then looking across 10 sheets, again in the same column - D.

These are the formulae i have tried. the 1st works on the sheets being
called sheets 1,2 etc and not being renamed and the 2nd formula allows you to
name the sheets then refer to them seperatly. i would like to use the 2nd as
i all my sheets are named.

=VLOOKUP(B1,INDIRECT("sheet"&MATCH(TRUE,COUNTIF(INDIRECT("sheet"&ROW(INDIRECT("1:10"))&"!d2:d100"),B1)>0,0)&"!d2:d100"),1,0)



=VLOOKUP(B2,INDIRECT(""&INDEX($A$1:$A$3,MATCH(TRUE,COUNTIF(INDIRECT(""&$A$1:$A$3&"!d2:d100"),B1)>0,0))&"!d2:d100"),1,0)


I either get the response N/A or VALUE. i dont know if i have got all the
referenes correct, maybe thats why its not working.

maybe the "d2:d100" is incorrect as i repeat it in the formula, but this is
the range where the lookup should look in.

I hope im making sense.

Thanks for your help.

For a VLOOKUP to function with an offset of more than 1, the LookupRange must
include the columns that contain the data to be returned as well as the
column that contains the value to be looked up.........

=VLOOKUP(A1,A:A,1,FALSE) will work...
=VLOOKUPiA1,A:A,2,FALSE) will not....it should be -VLOOKUP(A1,A:B,FALSE)

But i am looking in a number of sheets, how can i tell this formula to lookup
c:c in each sheet. the thing is because i am only looking up names i just
need to see if the name on one sheet is present anywhere within the 20 sheets
and it doesnt need to return anything other than "1,false" which means just
to return the name IF it appears anywhere within the 20 sheets.

thanks.

Sorry, I guess I missed your point. I've never done exactly what you are
attempting, but I think my first choice would be VBA.....and my second would
be to use a helper column with the 20 individual VLOOKUPS there and then use
one master VLOOKUP to check that column for results...........just my
thoughts...

Maybe you overlooked the formulas that i have been playing around with..


=VLOOKUP(B1,INDIRECT("sheet"&MATCH(TRUE,COUNTIF(INDIRECT("sheet"&ROW(INDIRECT("1:10"))&"!d2:d100"),B1)>0,0)&"!d2:d100"),1,0)

=VLOOKUP(B2,INDIRECT(""&INDEX($A$1:$A$3,MATCH(TRUE,COUNTIF(INDIRECT(""&$A$1:$A$3&"!d2:d100"),B1)>0,0))&"!d2:d100"),1,0)

i got these off previous posts on this website, where people have been
provided formule to work through, i tried to apply it to my situation but it
didnt work.

if not via formula, how do i do it via vba?

please help, i really dont know what to do.

This may get you started.........

Sub FindTheName()
Dim sh As Worksheet
Dim searchname
Dim k
Dim iCount As Integer
iCount = 0
k = InputBox("Enter NAME to search for:") 'case sensitive
searchname = k
For Each sh In Worksheets
sh.Select
Dim lastrow As Long, r As Long
lastrow = Cells(Rows.Count, "D").End(xlUp).Row
For r = lastrow To 1 Step -1
If Cells(r, "D") = k Then
MsgBox "Name found on " & ActiveSheet.Name & " in cell " & Cells(r,
"d").Address '"tom"
iCount = iCount + 1
Else
End If
Next r
Next sh
If iCount = 0 Then
MsgBox "NAME NOT FOUND"
Else
MsgBox "NAME FOUND " & iCount & " TIMES"
End If
End Sub

Your 2nd formula works but you have mismatched references:

=VLOOKUP(B2,..........,B1)............)

Both of those references need to the same.

Also, don't forget that this is an array formula. Array formulas need to be
entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER)

I have now used the formula from your example sheet:

=VLOOKUP(A2,INDIRECT("'"&INDEX(WSList,MATCH(TRUE,COUNTIF(INDIRECT("'"&WSList&"'!A:A"),A2)>0,0))&"'!A:B"),2,0)

This works ok, expect the formula returns back information that i dont
really need, i understand this is because of the "2,0" but when i change it
to "1,0" it doesnt work! i do no want it to return anything additional back,
for example, as i am just searching for peoples names in the 20 sheets to see
if they are present i just want it to return the persons name if they are
present, i do not require any additional information being returned.

how can i change the formula to do this?

thanks alot.

when i change it to "1,0" it doesnt work!

Hmmm...

It works for me.

However, if all you want to do is verify that the name appears on some other
sheet try this instead (normally entered, not array entered although it'll
work either way):

=IF(SUMPRODUCT(COUNTIF(INDIRECT("'"&wslist&"'!A:A"),A2)),A2,"")

Thanks for the new formula, it worked when i tested it on 3 sheets but when i
tried to make it work for what i need it for (which are 31 sheets) it doesnt
work!

This is the formula i changed to new cell references:

=IF(SUMPRODUCT(COUNTIF(INDIRECT("'"&WSlist&"'!D:D"),A2)),A2,"")

I just keep getting "REF!". I have the sheet names re-named in the exact way
they appear on the sheet tabs and they are in the named range "WSList", the
data that i am looking up is in column A (which is in the sheet where i am
doing the formula which is an unnamed sheet1) and in all the other sheets i
need to look in column D.

what am i doing wrong?

please help. thanks.

I tested the formula on a file with 32 sheets and it worked ok.

Is the defined name WSList a static range or is it dynamic? If it's dynamic
you'll get a #REF! error because INDIRECT won't interpret this correctly.
Are there any empty cells in WSList? If a sheet does not exist (yet) but the
sheet name is in WSList then you'll get a #REF! error.
what i need it for (which are 31 sheets)

31 sheets for the days of the month? If so, what are the sheet names? 1, 2,
3 .... 31? If the sheet names follow some sort of sequential pattern you can
eliminate having to create the WSList.

Its worked fine now, i dont know why it chooses when to work and when not to
work! Just for future reference, what do you mean "is the worksheet list
static or dynamic"?
Also, its not days of the month.. its a list of job roles across the
organisation so follow no sequential order.

thanks.

Sorry to bother you again but i just wanted to ask if there is a way to get
my formula to work as part of a macro or a vb code? If i leave it as a
formula then this means that the same sheet will have to be copied across
into each new months file, i would like a button to just do the job instead -
find the info required and put it in a new sheet that it will automatically
be re-named "lookup". is this possible?

also, i am looking to do another type of lookup only this time i have 3
different sources of information and i have to do 3 different lookups between
each source to find out which staff member is on each:

whose on source 1 and not on source 2
whose on source 2 and not on source 1
who is on source 1 that is also on source 3

is there a quicker way around this? or would it jus be 3 different lookups?

thanks a lot for your help, really appreciate it.

I have posted the below in the programming forum but no reply as of yet.

Meanwhile, I have another question regarding the 'worksheet function' side:

The formula below allows me to lookup 1 colmun in sheet 1 into column E in
20 different sheets.

=VLOOKUP(B2,INDIRECT("'"&INDEX(WSlist,MATCH(1,--(COUNTIF(INDIRECT("'"&WSlist&"'!E:E"),B2)>0),0))&"'!E:E"),1,0)

I now need to look the other way around i.e. whats in the 20 sheets that
isnt in sheet 1. so, instead of 'lookup B2 in WSList' (which is my sheet
range).. i need to lookup WSList into B2. i tried altering the formula abit
but it didnt work.

how do i do this?

thanks a lot.

I posted on the programming forum but no response and i am in urgent need of
help! normally i used to get replies from these forums in minutes but now its
coming to days, is there any reason for this?

hope you can respond asap.

thanks.

Can't be done with a single formula.

It sounds like you should consider hiring a consultant! <g>

It's probably due to the complexity of your request. The more complex the
problem, the fewer people there are that are qualified to solve it and less
of a chance that one of these people will see your request. And then, how
many of those are willing to spend the time to solve the problem (for free).

Hi,

Are you not able to offer a bit of guidance as to how i can get around this?
how many formulas and what type?

i really appreciate your help.

You need to have formulas on each of the 20 sheets, 1 per lookup_value, that
does a lookup back to the sheet1.

You can only do so much with formulas. What you want to do isn't possible
with a single formula. If you don't want to go the route I've outlined above
then your only other choice is a VBA coded procedure. This procedure would
not be a trivial matter and this relates to my other reply about why you
might not be getting "quick" responses. The more complex the request, the
less chance of getting a "free" solution.

Think of it this way: I'm looking for volunteers to either change the
transmission in my car or wash the windshield. Which task is more likely to
get volunteers?
