Urgent website problem

Hi guys,

big problem with my site and i have no idea how to fix it!

I have an animated scrolling bar on my homepage, it no longer works and the arrows either side have stopped working. https://www.completemuscleandfitness.com

I was running Yslow after having some loading problems, it’s possible i have clicked ‘add as CDN’ under grade. In fact i’m pretty sure i have done this, could this have caused the problem? If so how can i fix it?

I did a backup of my theme a few days ago, i’ve just copied that over to my server with no success.

Please help…
