Lightbox affecting JS slider


I was just wondering why the use of lightbox is affecting the javascript slider.

Take a look at this page:

The images down the right are clickable(lightbox)

Now the header should be a JS slider like on this page:

Notice the slider works on this page.

Can anyone help me find out why this is? How can i fix this?

Thanks again

When i take out this line:

<script type="text/javascript" src=""></script>

The Js slider at the top of the page in the header works, why is this?
