My misaligned shopping cart...

In Firefox, everything looks fine. But in IE everything hides beneath the right side boxes. I've removed the side boxes to see if it would help, but it made things worse by stretching all across the page to the edge where it gets cut off again. Can some one help? I greatly appreciate it.

Your mainpage starts out mis aligned

You main image is 600px wide plus margins & padding and l&r columns about 150px each and you have this set to be 900px wide

Try 950px for the main wrapper and see if that assists

Tried it, it didn't work. It made it look a lil better in Firefox though. Does any one know why it looks ok in Mozilla Firefox browser but horrible in Internet Explorer? Does n e one think this could be apart of my shopping cart abandonment?
