Help using lookup function

[Guest]

I'm having trouble using the lookup function.

I have numbers that look like this in a list, although it's only part of
what I'm using:

-11 2179
-10 2420
-9 2661
-8 2897
-7 3123
-6 3332
-5 3521
-4 3683
-3 3814
-2 3910
-1 3970
0 3989
1 3970
2 3910
3 3814
4 3683
5 3521
6 3332
7 3123
8 2897
9 2661
10 2420
11 2179

When I use the lookup function on another sheet of the cell, it does not
look up the proper value always. My columns go from (-100, 100). Outside
the values of (-10,10), the lookup works properly.

These are the lookup cells:

-11 2179
-10 2420
-9 2420
-8 2897
-7 3123
-6 3332
-5 3521
-4 3521
-3 3814
-2 3814
-1 3910
0 3989
1 3989
2 3910
3 3910
4 3683
5 3521
6 3521
7 3123
8 3123
9 2661
10 2420
11 2179

If you'll notice, the values that the lookup cells get are not the values of
the cell they're looking up, but often one off.

Any suggestions on why this might be happening?

What is your lookup equation?

 

[Guest]

For instance, the equation for the cell that is to the right of zero is
"=LOOKUP(A104, 'Issue 1'!$E$2:$E$102, 'Issue 1'!$H$2:$H$102)"

 

[Peo Sjoblom]

If you are looking for an exact match use vlookup or index and match combo

=VLOOKUP(A104,'Issue 1'!E2:H102,4,0)

or

=INDEX('Issue 1'!H2:H102,MATCH(A104,'Issue 1'!E2:E102,0))

For some reason, neither suggestion gives values all the time now.

Often, I get the #N/A error. However, there most definitely is a value
among the series the corresponds, so there shouldn't be an #N/A error.

Did you import this? If so you might have hidden spaces trailing html
characters, I just make a quick test and copied the table for your post,
pasted into excel and applied a vlookup formula typing in the lookup values
and those that I tried I got a correct hit, no errors at all so I can only
assume that what you think is a match is not,
you can test with a cell that you know should be correct and then compare
them =cell=cell2 or even check how many characters

=LEN(lookup_Value_cell)
=LEN(value_from Table_cell)

same number?

Yes, I did import them.

When I did those tests, they indicated that there numbers were imprecise and
had been rounded for display purposes. I used the ROUND function, and then
they all came up as TRUE when using that test and with equal numbers using
LEN.

Still however, the error persists.

 

[Peo Sjoblom]

You might need to round in both instances

=INDEX('Issue 1'!H2:H102,MATCH(ROUND(A104,2),ROUND('Issue 1'!E2:E102,2),0))

entered with ctrl + shift & enter

other than that one value might be text and the other number, try this

=ISTEXT('Issue 1'!E2)

copy down and see if you get any true values, do the same with your lookup
values

I get false on both instances when I use ISTEXT on every value.

The index function yields #VALUE. Perhaps I don't know exactly how to work
it?

Should I send you my actual file?

 

[Guest]

Somehow, when I use the ROUND function now, it all works. It didn't work
last time, and I still had it in there, but then it started working when I
opened the application again.

Thanks!
