Rather than start a new topic this seem to be to most appropriate place to ask:

If I click on Flag This Video I get no popup and once I click on it I get an error on page in the bottom left in IE7 obviously double clicking on this shows me what the error is:

Line: 1
Char: 1
Error: Object expected
Code: 0
URL: (this is unimportant as it affect all videos)

I've tested it with firefox and again no pop up but then I dont get an error message.

Any suggestions? Thanks in advance :)
