hi XLUser

You can use the beforeclose event in the Thisworkbook module

Try this tester for the cells A1,A3 and C1

Private Sub Workbook_BeforeClose(Cancel As Boolean)
Dim response
If Application.WorksheetFunction.CountA(Sheets("Sheet 1").Range("A1,A3,C1")) < 3 Then
response = MsgBox("Are you sure you want to close, not all cells are filled", vbYesNo)
If response = vbYes Then
'do nothing
Else
Cancel = True
End If
Else
'do nothing
End If
End Sub

I would like to setup a function similar to a web-based function which
informs users that all required information has not been completed and to
please complete all required fields. I would like to be able to allow them
to close the spreadsheet even if required fields are not completed.

Does anyone know how to setup such a functionality in Excel?
