Div Tags: Added a sidebar to my page and it broke

[Snot]

I was trying to add a div sidebar to my page and it worked great on the top half but the bottom half move over.

Can you see what I am missing its got to be something simple.

EDIT

LOL it might help if I upload my css file.

Do you mind looking again hehe the sidebar falls through the bottom of the page instead of pushing it down.

Any ideas?

Yes, that would help. And also a link to the site in question.
