Can't edit products in Safari or FireFox

I'm not able to edit my products besides in Internet Explorer. Works great, but in Safari and FireFox I can only edit the first product. The rest of them when you choose edit it takes you to a blank page....

Thoughts?

I figured out the problem. When I was embedding some javascript it was giving an error.
This was the script, anyone have any clues?
