Erm.. I see that you have kept your original script and just added mine as a completely independent script
. You've even kept my reference to non-existent carousel, etc., pages - so no wonder it won't work.
You need to combine my script with yours - that is, with your goForit() function. If you have no idea how to do this then I can't help you any further and perhaps you should consider hiring someone to do this for you.
Good luck. Andy.
