MyBB Community Forums

Hi guys, i have managed to integrate MyBB with my website layout and it looks pretty good i must say for my first try. However i am having a weird issue with my menu, im not sure if it pertains directly to the template itself or something to do with MyBB. At any rate, the problem that i am having is the menu (javascript) seems not to work when being viewed in any mozilla based browser (Opera, FF, Chrome etc). However it works just fine in IE. Here is the direct link to the forum, feel free to poke around and tell me what you think and or if you see an issue that i need to correct.
