It worked fine for me in xl2003, too.

What error message did you see?

Which line caused the error?

Dim myRngToInspect As Range

Set myRngToInspect = Sh.Range("C300")

If Target.Cells.Count 1 Then
Exit Sub
End If

If Intersect(Target, myRngToInspect) Is Nothing Then
Exit Sub
End If

If UCase(Target.Value) = UCase("QC") Then
Sh.Tab.ColorIndex = 3 'red for me
Else
Sh.Tab.ColorIndex = 2 'White for me
End If

End Sub
