Doesn't work in blog posts

[9BadWolf9]

It works on main page but doesn't work when the user navigates in another page.
Correction:It seems that if I add a script inside the post, the javascript for the navigation isn't working, even thought they are completely different. my site is http://spotlightsontheredhead.blogspot.com/ if it helps you understand what I mean. Seems like it has trouble playing along with the lookbook widget.
