VLOOKUP calendar dates

[Guest]

I have a sheet that has 5 columns
(DayName,CalendarDay,Impact,Holiday,Result). The basic idea is that it has
every day in the year listed (and actually goes out to the beginning of
2008). The Impact column is what holds the modifier for dates. If there is a
holiday then we have to add a Plus/Minus modifier in this column which tells
the formula to add or subtract days for cutoffs on delivery or receiving. Now
what I am trying to do (from a module not formula because formulas get to
messy in large spreadsheets) is write a function that does a lookup on this
page and returns the Impact for that day of the year. However, when I run my
code I get NOTHING, ZIP, not even a ZERO back. I put error code in to see if
the code was getting an error and nothing.

Also if anyone has a better example for the data section I am ready to hear
it. At this point I figure to cut the page data down by removing days that
have 0 Impact. I have inherited this spreadsheet and I am trying to update it
to work better. We have several people who use versions of this spreadsheet
and make mistakes on it because they do not understand the formulas, so I am
putting all that I can into modules.

It sounds to me that you are trying to emulate the NETWORKDAYS Analysis
Toolpak function, which calculates days between two dates, and can ignore
holidays.

Actually no that does not help at all. If the day that a item is shipped out
falls on a holiday I need to calculate weather to set the cutoff earlier than
that day or in the event that an item in scheduled to be received on a
weekend and the monday is a holiday then I need to advance the pickup date
beyond the holiday or weekend. The weekend part is not a problem it is the
lookup of the holidays.

This one does it:

Function doLookup(data)
On Error GoTo ProcessError
If LCase(data) = "omit" Or data = "" Then
doLookup = 0
Exit Function
End If
Dim data1 As Double
data1 = data
Dim myRange As Range
Set myRange = Range("$B$4:$C$1100")

MsgBox (Application.VLookup(data1, myRange, 2, False))
Exit Function

ProcessError:
MsgBox (Err.Description)
Resume
End Function

But there are still problems with your error routine, which is in an
infinite loop

Thanks that helped.

End If
Dim data1 As Double

Set myRange = Range("$B$4:$C$1100")

MsgBox (Application.VLookup(data1, myRange, 2, False))
Exit Function

ProcessError:

Resume
End Function

So how about putting the holidays in a list, say M1:M20, and use Conditional
Formatting on the pickup date (say cell D2)with a formula of

=ISNUMBER(MATCH(D2,$M$1:$M$20,0))
