Hi I'm trying to get flash to talk to JavaScript functions. I have so far been successful and have it working in all browsers besides Mac IE and Netscape it brings up the following error

"Microsoft JScript runtime error:
Object doesn’t support this property or method"

The line of code in question:
return themovie.PercentLoaded() == 100;
Basically the site was set up with users without the flash plug-in in mind. Therefore the main navigation remains, simply the flash doesn’t display if a user doesn’t have flash. The site can be seen at: http://verify.idp.com/ieltsaustralia/
My JScript is supposed to call a function which makes the flash movie jump to a certain frame. Any help of suggestions would be valuable.
