Ok guys..

I have a huge problem. I am building a website for my company and came in half way through a project to finish of a website. The site is designed using dreaded tables and dot net nuke.
Naturally tables are not my option but the option of the project manager, however that is not the problem..

I am having trouble with a header, navigation gap in internet explorer and have tried every trick in the book to make it vanish..
This would normally be very easy to fix, however take not ethat I am talking about a cms with its own set of resets and tables..this may be an easy fix but I just cant see it

lpa-group.directcms.co.uk is the testing server that I am building the site on.

The problem is that in IE the gap is to big between the header and the nav

I look forward to your advice
