On line 28 of the source code, you have some carouslide jQuery code that expects the jQuery library to already be loaded.
Currently your jQuery library is being loaded at line 361.
Either move it above the carouslide code, or move the carouslide code below where the jquery library is loaded.
It also seems that you’re not loading a library for carouslide, which is something else that you’ll need to deal with before that will work.
I had a bit of a shuffle around this morning, and in the end placed everything to the top of the page, and the same scenario persists, where by the slider isn’t working and the fancybox does. So checked on your other issue which was library not loading, and couldn’t find anything that wasn’t there, as in all the files needed are on the server, and the error which I can now see -
TypeError: jQuery(...).CarouSlide is not a function
jQuery(".featured-slider").CarouSlide({
On line 30, and cant see what it means, which I think is what your referring to is it.
The trouble is before I added the fancybox the corousel worked fine, and that’s why I went for the conflict issue.
