Hi guys, I can't seem to figure out why IE6 won't render my page properly... I'm using margins and not padding - pretty sure I don't need the box model hack on any of my divs??

everything below the nav is right shifted...

btw renders fine for me in ie7,ff,safari

any help much appreciated! Thanks so much guys!!

Here's the link and Here's a screen if you don't have ie6
