On my site that is currently under constructions, the right menu moves over the main table when i push on the "nánar link"

could anyone tell me what is wrong with this??

The leftmenu is exacly the same in the .css file but the postition are different, shouldn´t he move also over the main table then?

I don´t know much in css style so could you tell me exacly what is should write or change in the layout3.css file

the site is @ www.britney.is/new/index.php
