Hi guys, sorry to have to burden you guys with this but I'm having a problem with layout on ie6 & ie7

I've been busy re-vamping my site on my local drive and had tested it in ie8 and firefox and chrome (still trying to figure out how to get more than 1 verison of ie on my machine) and I put it live without testing it on ie6&7 and wouldn't you know it doesn't look right.

This site is live now with people shopping on it, if anyone knows what I need to do to fix this really quickly I'd love them for the rest of my life!
