jQuery Tools Not Loading Correctly

Hi,
I’m currently working on a site - see the test version here: http://thgcreative.co.uk/yeti/

For some reason I couldn’t get jQuery Tools to load unless I called the jQuery Tools script within the body of my file, just before the code was needed for a slideshow. Something was causing a conflict, but as I got the code to work I was fine with it leaving there in the body. However, now I am trying to create a mobile version of the site and using Enquire.js to call jQuery Tools, as we don’t want this script to be loaded on mobile devices.

Now, even though I’ve got the script to be called in exactly the same place as before, which was just inside the #content_inside div it doesn’t seem to work and again, there is some kind of conflict.

What could be causing this? I’ve looked at the console in Chrome and seen the “Uncaught TypeError: undefined is not a function” message, which means that jQuery Tools is not being called for some reason. Does anyone have any idea what could be causing this?

Thanks,
Russ
