Please help newbie

Hello, though I've been designing and implementing sites for a while, I'm new to doing a CSS site. I have everything working and it looks great on my computer and several others. But it seems it's not working in IE6 - I'm not sure what isn't compatible, but the whole menu bar displays on top of itself and the sidebar column goes below the main content. It's a mess. Please offer me any suggestions. Here is the link: www.precoinc.com/07/
main.css is the primary style sheet, with menu.css being the other. Let me know if you need any further info. Thank you in advance!

You might try getting rid of those IE6 and 7 conditional tags. It seems to display better without them. Just make sure you don't lose the </a> tags that are in between them when you delete them.
