Formula that returns the last valid value found within a range

[electrox]

Hi guys,

I've having a little problem with the LOOKUP formula, I have a range of 31 sheets "1:31" where there might be data in their cells , for sake of this examples let's use A1

So we have 31 A1s in a range of "1:31" and then I will create a Sheet "32" where its A1 needs to return or be equal to the last valid data found in the prior 31 A1s of the range.

So if the last of the A1s that has data is on sheet "20" then the A1 on sheet "32" has to be equal to A1 on sheet 20.

=LOOKUP(2,1/('1:31'!L5<>""),'1:31'!L5)

This formula should do the trick or am I incorrect?( I'm not an expert I'm just following what I have found on the internet )
The problem I have while I'm updating the range on this formula is that once is hit enter it transforms into this =LOOKUP(2,1/('1:[31]31'!L5<>""),'1:31'!L5) and I just get a #REF! error

Would greatly appreciate any help

Thanks!

Here's a UDF :

Function LDC(rw&, col&)
Dim c&, x
For c = 31 To 1 Step -1
    If Sheets(c).Cells(rw, col) <> "" Then
       LDC = Sheets(c).Cells(rw, col)
       Exit For
    End If
Next
If LDC = 0 Then LDC = ""
End Function

To use it : on sheet 32 enter in A1 =LDC(ROW(),COLUMN()) and fill across and down as required.

What version of Excel are you using?
I suggest that you update your Account details (or click your user name at the top right of the forum) so helpers always know what Excel version(s) & platform(s) you are using as the best solution often varies by version. (Don’t forget to scroll down & ‘Save’)

Thanks! I'll give it a try!
