I am also trying to implement fancybox on my site as well but have run into problems when testing the site. I think it's because of the different versions of jQuery that the fancybox code uses. It calls for 1.4.2. 

I've tried messing around with putting in jQuery.noConflict somewhere, but really am pretty new to all of this and don't know what I'm doing at this point!

What information/links do you need me to provide to help me figure this out?
