Flash and Javascript is blocked on one page checkout! Help needed!

Guys, I need to execute Flash or Javascript on one page checkout, but it somehow gets blocked. Any thoughts?

Check to make sure that /lib/jquery/jquery.js is as per the release, the directory permissions are correct.

cs-cart’s scripts work just fine.

I need to have 3rd party scripts work on checkout page. I believe one page checkout is disabling some 3rd party scripts on the page.
