Alright well I solved the problem, but in a way I really didn't want it to be solved.
In the showResult function I removed the event listener and just called a function called "clickzorz". Then I just made a function called clickzorz that had the event listener and everything works fine now.

Knowledgable n00b
did the error come with any additional text?

Why don't you use double line (//) comments in your code and use [HIGHLIGHТ=actionscripit][/HIGHLIGHТ]tags instead of "code"
Your code is absolutely unreadable
