Lightbox not working... conflict?

Hellooo. I’m trying to use lightbox on some images but it’s not kicking in and doing it’s magic.

The images in question are the three identical thumbnails under the welcome video and first block of text.

I’m pretty sure everything is correct, I’ve taken it all out and put it back a couple of different ways, all with no effect.

As a test I uploaded the example lightbox page and this works perfectly.

It uses the same Lightbox files (CSS/JS) as the attempts on my own page which makes me think there’s something in my own code that is stopping it from working…

Any thoughts?

Thanks in advance.
