Question
Hi Tom

I have written the following formula:

=IF(AG1=AM1,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE) IF(AH1=AM1,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE) IF(AI1=AM1,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE)  IF(AJ1=AM1,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE) IF(AK1=AM1,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE) IF(AL1=AM1”,VLOOKUP(A2,\$A\$S2:\$A\$T200,2,FALSE)))))),””)

Is it possible to write this in VBA?

==<added usage example at the bottom>===

first, your function isn't really a legitimate function so it leaves the request open to interpretation.  I would think what you are actually asking is this:

=if(isnumber(match(AM,AG1:AK1,0)),Vlookup(A2,\$AS2:\$AT200,2,FAlse),"")

Then when  you say VBA, are you looking for a userdefined function written in VBA that you can use in a worksheet.  If so, then I see 4 Ranges that would need to be passed to the function plus the column to return.

r1:  would be the value to find in range r2.  In your example, cell AM
r2:  would be the range of values to find r1.  In your example, cells AG1:AK1
then the look up values
r3:  would be the value to find in the vlookup function. In your example A2
r4:  would be the lookup range.  In your example \$AS\$2:\$AT\$200 (I think)
icol:  the column of the value to return in the lookup range .  column 2
I will assume you want an exact match so the function won't look for the 4th argument of Vlookup - the False

this works for me as I designed it. I don't know if it is what you want:

It should be placed in a general module (in the VBE, Insert => Module)

Public Function MyVlookup(r1 As Range, r2 As Range, r3 As Range, r4 As Range, icol As Long)
Dim ans As Variant, v As Variant
Debug.Print r1.Address, r2.Address, r3.Address, r4.Address, icol
ans = Application.Match(r1, r2, 0)
v = Application.VLookup(r3, r4, icol, False)
If IsError(ans) Or IsError(v) Then
MyVlookup = ""
Else
MyVlookup = v
End If
End Function

here was how it looked in a cell:

=myvlookup(\$AM\$1,\$AG\$1:\$AL\$1,\$A\$2,\$AS\$2:\$AT\$200,2)
