Whenever you see "Syntax error", 99.9% of the time it's a Javascript error. Quite often it relates to a script that hasn't been called.
In your case, my suspicion is here:
Code:
<script type="text/javascript" src="http://upmarketontent.com/images/vernavbar.js"></script>
You're missing the "c" in Content.
Start there, see if that solves your issue, and if not, then I'd suggest getting either Netscape or Firefox and when the page is loaded, type "javascript
:" (with the colon, but without the quotes) into your address bar.
Edit: two things I've also noticed.
1) You don't have to put in the "http://www.upmarketcontent.com" part when calling scripts/images on your own server. Just use a path relative to the root directory (e.g. /images/picture_on_the_top_left.jpg as opposed to
http://www.upmarketcontent.com/image...e_top_left.jpg). It will help to prevent the error described above from happening.
2) You should keep your scripts in their own folder (not images) so that your site's easier to maintain and you're not going through 1000 files trying to find one.
