Menu sessions

[eluser]Jesse2303[/eluser]
Hi all
My login works again, and I've made 2 sessions, you can see below.
When I log in with my login. Everything works fine but only the menu won't update. What I'm doing wrong ?

O, the autoload.php , I added sessions too to the array.

Code:

$this->session->set_userdata('login', '1');
            $this->session->set_userdata('gebruiker', $_POST['name']);

Code:

<?php
        if(isset($_SESSION['gebruiker'])){
    ?>
            admin     <?=anchor('dashboard', 'dashboard');?> begin
                  - <?=anchor('login', 'uitloggen');?>  
            modules <?=anchor('pics', 'afbeeldingen');?>  
                  - <?=anchor('nieuws', 'nieuws');?>
    <?php
        }
            else
        {
    ?>
        gast  <?=anchor('main/index', 'begin');?>
            - &lt;?=anchor('main/login', 'login');?&gt;</a>
            - &lt;?=anchor('main/contact', 'contact', '');?&gt;</a>
    &lt;?php
        }
    ?&gt;
