Javascript problem

[ishare]

Hi,
I need help with javascript. And its really quite important for me to solve this problem.
I would like to use a tab panel in my current showthread.php
I did add the .css styles and also the javascript (.js) code to the root directory. Everything is fine.
But due to a reason i do not know, vbulletin convert the links.

The tab example :
http://www.divx-world.com/tab.html

So the link of tab1 and others should be like "javascript:;" but vbulletin convert this link to "javascript%3Cb%3E%3C/b%3E:;"

Please help me about this problem so i can solve it.

Thanks in advance...
