Simple CSS Positioning Issue

So close... but so far, thanks to IE. I am trying to get the ads on the following page to position correctly, which they do in FF and Safari:

www.freelancereview.net

But the smaller ads are getting pushed down in IE. Any idea what is causing this and how to fix?

Fix the errors in your markup first, see http://validator.w3.org/check?uri=http%3A%2F%2Fwww.freelancereview.net%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

Hello cmcconnell,
Ab is right, there is a lot there you can easily fix.

To stop your float drop, try removing the width from the containing div... like this I think -
div#bsaz_1242348.adblock {
/*width:100%;*/
display:block;
}
