of active sheet where I copied this code in worksheet module,its infenitely
activating that other_macro whenever I am opening that sheet.I put date value

If fDate Then
ans = MsgBox("Proceed?", vbYesNo)
If ans = vbYes Then other_macro
End If
End If

'This is worksheet event code, which means that it needs to be

'the View Code option from the menu, and paste the code in.
