Hi Jackie,
Point them at this Forum thread for that script error I'm seeing. That's easy to spot with IE. Just look lower left on the browser window Status bar just above the Start button and you'll seeing the yellow warning ! with "Done, but with errors on page.". Double-click that and you'll see the cryptic message about "Error: 'document.getElementById...".
That will get them looking. That piece of script is at least one problem.

Edit: I took a second look at the two failing links. I don't see anything obvious for problem with the anchors for them. My guess is a problem with the path for the call, which means that page either isn't on the server or the file name is different.
