Because your'e using ElseIf, both statements (interiorColor=3 & 41) are
evaluated within each second that's why it's not noticable the changes, use
instead Else as follows:

With Sheets("Serie A")
If .Range("AN6").Interior.ColorIndex = 3 Then
.Range("AN6").Interior.ColorIndex = 41
.Range("AN6").Value = "Champ"
Else
.Range("AN6").Interior.ColorIndex = 3
.Range("AN6").Value = "Champ"
End If
End With

"MAX" wrote in message

Will you please tell me what's wrong with this code?
