Hi,
System should force users to classify the excel documents as Internal, Public, Confidential before they close.
1. I want the classification option to be provided as radio button in alert message box
2. User cannot close the message box unless they choose any option
3. If the user closes the inner (x) close button also, the macro should trigger
4. When user classify a excel today as Internal and open the excel tomorrow and close (with or without making changes), then also the alert message box should show.
