Design problems.

Any regulars may have noticed that my categories have not been working since i changed the design of this site. I'm hard at work trying to fix it. As i use labelr.com (which calls on an external .js file) so i can't exactly see what i've done wrong. I have contacted the guy who runs labelr to see if he could check my code, i'm hoping he get's back to me soon. Oh well i'll let you know how it goes. But for now don't bother with the categories links in the sidebar.
