Need some help with some jQuery effects

On my site here, I am using the coda slider effect I found here here. And on the tab entitled "Home Groups", there is a link "Home Group 1", which links to a fancy zoom box that I got from here here.

But when I click on the fancy zoom text it scrolls the container a little to the right, and on some older browsers it returns to the original first container that loaded from the start.

Any idea where the effects are conflicting? or what code I would have to amend to make it work more fluidly?

Any help would be appreciated as I'm new to jQuery, and discovering how wonderful it is, but still don't quite grasp it all.
