Forum href="#" not working in VB?
 

I have a link;

Code:
do something
This link executes a javascript function and works perfectly fine outside of vbulletin but, when I dump the code into vbulletin, clicking that link takes me to the forum root (mysite.com/forum/forum.php). My question is, why? Clicking that link in a local test html page simply executes a function and does nothing. What is vbulletin doing?

How can I create a link that goes no where but executes a function in VB?
