3.0 menu’s

Hey all,

I’m still struggling alot with the new menu intergration with 3.0. My theme isn’t ‘supported’ and im using the same code from the twentyten header and functions.php.

For now, im wondering the following. I’ve created 3 menu’s in the backend. One of them is a submenu wich comes back on every page.

How do I tell the code wich menu I’d like to include?

I’m using the following line:
<?php wp_nav_menu( array( 'sort_column' => 'frontpage', 'container_class' => 'menu-header' ) ); ?>
