Check for all task status when project is closed

I'm not overly familiar with how the Automation feature works at the Application level so I'll need to play around with that.

Also, on the Form rule that I built, the message that displays on Abort Save shows not only the message that I created but also all the criteria that needs to be satisfied in order to Save.  So the message is kind of messy.  Is there a way to exclude the criteria from the message?
