[jQuery] jQuery code not being run


Hi,
I'm working on a site with somebody, and we got most of it finished,
but it needs a little self made jQuery coding ...
The problem is that this isn't running at all!
The code is in personalized.js and is being loaded (firebug)
Code in bin: http://code-bin.homedns.org/205
We already tested around a bit but couldn't find anything that will
make it work, I think we also got a version using the var $j =
jQuery.noConflict(); but that might have been done wrong, theres a hide
() on mainContent just for testing but this isn't getting done
either...
The hole site is till now just for Firefox 3+ tested (and will break
in ie as far as i know)
The website: http://www.vonderdecken.net/
hope you can help since I'm totally new to javascript and jQuery. This
means I sadly also means I have not a clue at all how to debug it...
Oliver
