Div Layout with Footer?

This is my second site using div’s for the layout, and I’m having trouble putting the footer in. I think the problem is that my navigation bar on the left is longer then then center information. When I put a footer in, it just sits below the content to the right of the navigation bar. Here is the site, if anyone knows how to get a div (the footer) to go to the bottom of the page, let me know! It’s just a 2 column layout.


Any comments on the site would be appreciated also.
