[jQuery] Problem with form validation (works in FF, but not in IE)

[jQuery] Problem with form validation (works in FF, but not in IE)

Hi folks,
<a href="http://seifactory.com/login.php" target="_blank">This page</a> works in FireFox without problem, but doesn't do anything in IE. Now, I'm only talking about validation here, the form doesn't actually *do* anything just yet. All I was trying to do was get the validation going.
This is the first time I've attempted to use Jörn's validation plug-in, and I'm kinda getting the hang of it (or so I thought), but now this isn't working in IE so I'm all stumped. I'd like to figure this out before I try to work on learning anything else (like error message placement ... hints on that would be welcome too, though).
Thanks heaps everyone,
Chris
