HELP! Multiple clickTAG or score/shot counter!

Hi,
I’m having problem with my simple flash AS2 shooting banner/game.
I want user to shoot the moving object 5 times. After fifth shot user will be taken to a landing page. So it’s like a clickTAG but with 5 clicks.
I think I need some kind of score/shot counter and when the score will be =5 than gotoURL or something. Please guys I need your help!
