Hi all.

I have a spreadsheet that is emailed to someone to fill in. They then fill in some information and send it on to someone else.

Sometimes they don't fill in all the information so is it possible to have excel check that cells are filled in and to prevent someone from saving unless this is so? Or maybe a message stating that the cells need to be completed if Excel is being closed or saved?

First time on here. Any help would be greatly appreciated.
