IE display breakdown

[publik]

I am having trouble with this site displaying in IE. It displays how I want it in Firefox but takes a rather large dump when opened in IE.

I'm not sure where to go next. If someone could take a look for me it would be much appreciated.

OK a champ on another forum figured this out for me, I needed an invisible barrier below the header div and above the navbar to stop the divs being pushed up. Like this:

<div style="clear: both; width: 100%; height: 0; line-height: 0;
font-size: 0;">&nbsp;</div>
