When I debug it, its giving me an error right at the "Set rng=..." the same
one as before. I modified my code to read as such

Function Look_Up_Accross(ByVal What_I_Want)

Dim sStr As String, rng As Range
With Worksheets(1)
Set rng = .Range(Cells(1, 1), Cells(1, 256).End(xlToLeft))
End With
res = Application.Match(What_I_Want, rng, 0)
If Not IsError(res) Then
MsgBox "column: " & res
Else
MsgBox "Not found"
End If

Look_Up_Accross = res

End Function

Thanks

possibly you need to qualify the range elements - perhaps you have a
different sheet active this week than last.


Function Look_Up_Accross(ByVal What_I_Want)

Dim sStr As String, rng As Range
With Worksheets("Sheet3")
Set rng = .Range(.Cells(1, 1), .Cells(1, 256).End(xlToLeft))
End with
res = Application.Match(What_I_Want, rng, 0)
If Not IsError(res) Then
MsgBox "column: " & res
Else
MsgBox "Not found"
End If

Look_Up_Accross = res

End Function

Change to reflect the sheet that contains the lookup table.

Hi all

Can someone please explain why this isn't working? It is called from a
different Sub marco with What_I_Want being a text string I need to
match. It
should return the value of hte column as well

Function Look_Up_Accross(ByVal What_I_Want)

Dim sStr As String, rng As Range

Set rng = Range(Cells(1, 1), Cells(1, 256).End(xlToLeft))
res = Application.Match(What_I_Want, rng, 0)
If Not IsError(res) Then
MsgBox "column: " & res

MsgBox "Not found"

Look_Up_Accross = res
