Menu pushes content down....

I've tried everything and I cant figure out why this is happening...

Here is the css and the link to the site. The menu is menu_left, the boxes with the graphs are rightcol and leftcol, and the banner is intro_left

Thanks to everyone who takes a look at this...

In your HTML if you place your right div before the left div, it will solve your problem.
