Web design help

I'm having trouble with a site I'm designing. The nav menu at the top is rendering lower in firefox and opera than in IE7. The menu box is actually set around 20px below the gray box which is supposed to be containing it. It's probably something stupid that i'm missing, but i can't find it. If someone who knows what they're doing could look at it I'd appreciate it. Thanks in advance.

I notice you're using div tags. Div tags aren't the greatest things to use, as browsers interpret their positions differently. Span and tables are the way to go. )
