Hello,
I'm using jQuery 1.5.1 and the script works, but I get a "rootjQuery is undefined" error.(I also had to replace the </script> in RegExp with </script> or it wouldn't work at all).

Any possible soutions?

Thanks.

Right now, I've reverted to using jQuery 1.4.4; it seems some changes in the 1.5.x branch caused it to malfunction, but haven't gotten around to figuring out what exactly fails with it.
