[SWFObject] Firefox PC Express install not workin?

[MoD - Andy Reedman]

Hi,

Me again..sorry to be a pain...but Ive been fiddling with the express  
install and for some reason it's not working in Firefox on the PC?

Ive downgraded the flash version to 6....and set this test up:

Ive got the expressinstall.as and swfobject.js file in the same  
folder but somethings gone wrong somewhere?

Any ideas?

cheers
