Thank you everyone for your help over the past few days. I have most of the page done now. The submenu is still frustrating me! I have it positioned where I want it I just cannot get it centered. I have put the "margin: 0 auto;" everywhere and still now effect. In both FF and IE the further right I go on the menu... the more right it drifts.
