[SOLVED] Div Disappeared...?!

[math]

Hey, ik have a disappearing div.. it's this website i'm at: http://marktplaats.b-rainstorm.com/index.php (It's temporary in a subdomain.) it will come out to Dextromedia.nl.

 

However, the sponsor div is seen in Internet Explorer on the right side like it supposed to be (90px wide)

It's the black graphic, the rest is in dotted lines to view clear where it is..

 

the problem: Firefox does not show it... why?

 

I hope someone knows.. thanks for your time anyway

 

Here is the css t hat i wrote myself from a-z:
