Accepting offer web page error?

[OXX]

Group of us got our acceptance letters, went and logged in, went through the click-through, got to the job interest form, filled it out, and when clicking submit, it says "error on page" at the bottom. On further inspection, it says it is an invalid tag or some such on line 400 something, character 19. This happened on multiple computers running the recommended Internet Explorer. Emailed tech support.
Anybody else come across this before while accepting an invitation? Thanks.

The form worked tonight, thank goodness. If you encounter the error, or another saying that your selected date is no longer available, make sure you didn't click that you are interested in any of the classes. Click the first box or two that says something like "I am not interested in any classes at this time." Good luck and see you in January!
