jQuery bug

hey guys.

So im trying to learn some jQuery buy implementing jQuery onto my quiz site. But i have bug in my program that causes the "right answer" variable to show alot more then it's supposed to. It's like it loops trough the if-statement one more time everytime i click on a answer.

I realy cant find a solution to this bug so i thought i'd ask you guys.

You can find the quiz here: drinkquiz(DOT)comze(DOT)com

FYI, i'm fairly sure your site has a XSS vuln in your admin login.
It's accessible with a sql injection I believe.

Besides, I haven't learned any javashit because javashit is gay so I can't help you on the script.
