hello guys
i think i have a js conflict goin on here. basically i have a website with 3 included js applications.

1- coda slider - http://www.ndoherty.biz/demos/coda-slider/1.1.1/#1
2- jquery menu
3- jquery fancybox

you can see the website here:

the problem is all three are based on jquery, and the fancybox is not working. you can try it on the first thumbnail of the gallery.
