style help needed or damnd IE

[tpr]

Hi,
I'm working on a new style for my site (have a look at www.limudim.org/test).
Now it works perfectly on both firefox and safari but refuses to work on IE.
I've gone through the code at least a dozen time and sent links to friends but we can not understand why does IE show the page diffrently.

I would really appriciate any help you can offer since i've got no clue as to how to solve this.

Thanks in advance,
Tpr
