UDF producing #NAME?

[Jim May]

Both these functions are yielding/displaying the #NAME?
in cell A1 which contains either =ColumnLetter(AB5) or ColumnLetter($AB$5)
or
ColLetter(AB5) or ColLetter($AB$5)..
Any ideas as to why?
Thanks in Advance

Function ColumnLetter(Rng As Range) As String
ColumnLetter = Left(Rng.Range("A1").Address(True, False), _
InStr(1, Rng.Range("A1").Address(True, False), "$", 1) - 1)
End Function


Function ColLetter(Rng As Range) As String
ColLetter = Left(Rng.Address(False, False), _
1 - (Rng.Column > 26))
End Function

Best guess; you have the function definitions in a different workbook
from the workbook that you have the formulas in.

If the functions below are in your Personal.xls workbook (say), then
this:
=PERSONAL.XLS!ColumnLetter(AC15)

should work, but this:
=ColumnLetter(AB5)

gives me the result you describe.

You might also consider saving the functions into an add-in. (.xla)

Hi Jim,

Another version for you

Function ColumnLetter(rng As Range) As String
ColumnLetter = Split(Columns(rng.Column).Address(, False), ":")(1)
End Function
