TOPIC: Jscript error

I'm a novice when it comes to debugging but I have a menu item linked to DT Register to show events available for registration but I find then when I navigate to that page I cannot login/logout and I cannot view the google map. IE debugging says something like 'Breaking of JScript runtime error'. And 'Object doesn't support this property or method'. I don't get these errors or have any problems with any other pages. I'm not sure how to go about diagnosing the problem. Has anyone else had this problem?
