This is my first attempt to create something using Active X controls. I am
going to send some information to 3 different people and ask them to 1)
approve 2) deny or 3) request further information.

Do I want to use a check box or an option button?

Whichever I choose - how can i make it mandatory that only one of the three
boxes is chosen by the end user?

Also is it possible to share the workbook so that all 3 users can open it at
the same time?

Thanks - any help would be appreciated.
