CSS IE6 & IE7 compatibility work

Hi, Please check the attachment. It is a homepage design, including a header, a 5-button slideshow, and a few tabs. It looks fine in IE8, Firefox, and Chrome; but it is messed up in IE6 and IE7. Your job is to make it work properly in IE6 and IE7 browsers, looking EXACTLY like the other browsers. The interface language is Persian; don't freak out! Best Regards, Reza Riazi
