Hi,

Im very new to VB and would appreciate some help.

I need some code which compares two cells (AH1 & AI1) and if there is a
difference then the code runs a Macro (called DisplayCalendar)

Thanks

Copy below code in Worksheet Module (Right click on Tab , Click on
"View Code" , Paste below code)

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Range("AH1").Value < Range("AI1").Value Then
Call DisplayCalendar
End If
End Sub

Regards
