Lightbox not working eek!!!!!!!!!!

Hi guys,

Please you help, I am trying to create a gallery using the SPUN theme, where there are the circles, when you go over them they hover, you then click on them and get a lightbox. This is not working for me! I am tearing my hair out!

Using plugin :Lightbox Plus ColorBox (v2.6)

Please can someone have a look:

It displays two galleries of the same thing, the bottom one uses the lightbox but doesn’t hover and the top one does nothing?!

thank you!!
