jQuery Conflict with Shopp & Atahualpa

Hi:

I am setting up a website, and it has a gallery on the product pages that is not working. I have disabled all plugins, to see if this helped, but it does not. I also changed to the default WP theme, activated all of the plugins again, and the gallery started working (clicking thumbnails changes the main image and clicking the large image shows colorbox). I assume there is a conflict, but I am not sure what code to edit/add in the header.php. Can anyone help me?

Sample page, where this is happening, http://designsbymasselyn.com/butterc...ng-silver-band

Thanks in advance for any help!!!!
