Here's the version with iframes: (again ignore the links)

Problems I ran into: the pull down menus won't work when they overlap an iframe, so I had fall back on php include for that.
Also.. there's no easy way for the lower content iframe to automatically adjust it's height to the incoming content. Lots of folks online have this problem. I put in some javascript that does take care of that.
Down to 9 errors... mostly the missing img alt tag (which I'm bad about) but there are several that still have to do with the head info of the menu loading into that php include.
I need to see if there is a workaround for iframes and drop down menus.
Here's the page with the menu in an iframe: (in a div because I was experimenting with z indexing to see if it would help)
