RapidWeaver site only works in Safari. Help!

[Daveway]

I finished building a site using the latest RapidWeaver and it displays perfectly in Safari, but only Safari. It won't even display correctly in Firefox. I've looked through the code and can't see any problems.

Any suggestions?

While the HTML is valid, the CSS doesn't seem to be.

Two errors, but it's way to early/late for me try to make any sense of it...
