Link problem

[eluser]Gerep[/eluser]
Hi fellas,

I'm new here and trying to develop a quotation system but I'm having a little problem.

I have the menu with links like:

<ul>
<li><a href="user">Index</a></li>
<li><a href="quotation">Quotation</a></li>
</ul>

If I got it right, the first link will call my user class and execute the index() method. When I click on it for the first time it adds the user to the url like:

http://localhost/quotation/user

, when I click the second time, it will be:

http://localhost/quotation/user/user

and it makes all my other links wrong, like the Quotation:

http://localhost/quotation/user/user/quotation

Am I doing the right thing with links or there is another and better way to deal with them?

Thanks in advance
