IE6 users get everything shifted upwards 30-50px

I cannot, for the life of me, figure this one out.

If you open this in IE6, the navigation is hidden by the main content and I cannot get the CSS to position it correctly.

The best way to view all of the CSS is using an element viewer, like the one in Google chrome… if anyone is willing to help I can send the CSS files.

Thanks
