Created 3 custom menus?

I added three menus (Header, Sidebar, and Footer) and unregistered the default one by placing this in the functions.php file

    register_nav_menus( array(
        'header' => __( 'Header Navigation', 'twentyten' ),
        'sidebar' => __( 'Sidebar Navigation', 'twentyten' ),
        'footer' => __( 'Footer Navigation', 'twentyten' ),
    ) );
    function crec_remove_default_menu() {
    add_action('after_setup_theme','crec_remove_default_menu' ,11);

and assigned each menu to either of the three menus in Appearance>>Menus in the admin section
but this is the result,

whats the deal?

ok, got it, I had to edit the header.php file to point to the new menus name(header)
