RequiredFieldValidator [RESOLVED]

I'm using the RequiredFeildValidator to Validate my page. On the bottom of the page I have two buttons. One is to save the data to the database, the other is to return the user to the main menu page. The RequiredFeildValidator control works fine. The problem is I only want it to validate if the save button is clicked, not the return to main menu button. Any suggestions? Is there an attribute I can set in the button?

thanks

In the button attributes set:

CauseValidation = False
