Just looked again, and think I know what the problem is. You have no opening body tag on your page. If you open the HTML and look for "head", you'll see it open and close (/head), but after the closing, where there should be an opening body tag, there is none. JFBConnect (and browsers, and a lot of other things) need that opening body tag. We need it, specifically, because we search for it to inject some code into the very top of the page.
I think once you get that back in there, things will start perking up a little
Good luck, and keep us posted,
Alex
