a way to keep track of # of clicks

[Shawn Minisall]

Is there a way to keep track of the number of times someone clicks on a 
menu item in a prorgam?  What I want to do is make the rectangle 
disappear after they click on it at the main menu 3 times so visually 
show them they can't do it any longer.
