O.K. I see what you're talking about now, it's hard to spot.
Add <form style="margin:-15px;
If this is an IE only thing, and you use the margin setting I suggested, then you'll have to use a hack so the other browsers won't get the style.
You might have to check to see what the margin on the form is set to and include that value in the ma\rgin hack.
I think theirs most likely better way than using a hack though.
It has something to do with your layout, probably towards the top of the page, where you have something fugded.
Keep checking, you'll find it.
