You still haven't said *WHAT* the problem is.
Are you referring to the fact that clicking on the various tabs does nothing???
If I were guessing, I would say that probably you have two or more scripts in there that are interfering with each other.
I'd start by removing unneeded <script>s one at a time to see if the problem is fixed.
But this is what happens when you use scripts from all over the place without knowing exactly what each one is doing and when and how.
