Hi Welcome to Sitepoint
Have you fixed the issue as it doesn't look too bad in IE7 unless I'm looking in the wrong place?
You do seem to have some corrupted html at the top of the page where you have two doctypes and two head sections.

If you are using an "include" file for the body content then you should only be including the html that goes in the body and not a whole page with doctype and head section.
Clean that code up first and then we can carry on bug fixing once the code is valid.:)
