jQuery Forum

Ok so I have been racking my brain trying to figure this out for quite some time. I am using a Magento website, and generally only make edits in the backend so as not to mess up our current template. The problem I have noticed is when I make a CMS static block that calls for jQuery, it interferes with the jQuery that is already on the parent page else where, such as my drop down navigation. So either the navigation works or the block works. But both won't work at the same time. The static block in question is the list of videos displayed on the page that pops up using the prettyPhoto jQuery lightbox. Any help you can give me would be greatly appreciated. Here is the page in question.  if there is any other info that I'm lacking please let me know.
