Table ends abruptly on home page

[sgrizzle]

I am building a forum for which I started with a downloaded template to learn "what does what" on the forum so I can build my own style for the site. The problem I have is that in the forum category list, it lists three categories, then does a </table> and the rest of the categories just hang there with no formatting, backgrounds, etc. I can see the error, but I can't find out what template it comes from.

If you can't understand my description, checkout http://thetulsaforum.com/forum/index.php

Any help is greatly appreciated.
