Often users in my office select multiple sheets to print or for some other reason. Every once in a while someone will forget to ungroup the sheets before they start editing. This will cause the changes they make to happen in all the grouped sheets. This can corrupt the data in several sheets and waste a lot of time restoring them.

Is there a way I can have a message box or something pop up and tell the user they are about to edit a cell on multiple sheets? Thanks!
