works in IE but not Firefox? Why?

why doesn't this look right in Firefox

[natediggs]

I know the question usually goes the other way but this time I am stumped. I am a relative noobie when it comes to css. If anyone can tell me why this site is not viewing correctly in Firefox but looks ok in IE please let me know. Thanks in advance! Nate

do not advertise (even if unintentional) websites here. Post a page in question's code here, both it's CSS and it's HTML.

The problem is likely due to one of IE's hundreds of rendering bugs, or the fact that it's running in quirks mode because you did not specify a doctype.

To get help, you'll need to post all the RELEVANT HTML code and CSS code.
