Thanks! That works great! How can I do it with this additonal menu too?
<!– Lower Navigation –>
<nav id=”lower-navigation” class=”main2-navigation” role=”navigation”>
<h3 class=”menu-toggle”><?php _e( ‘Lower Menu’, ‘twentytwelve’ ); ?></h3>
<div class=”skip-link assistive-text”>“><?php _e( ‘Skip to content’, ‘twentytwelve’ ); ?></div>
<?php wp_nav_menu( array( ‘theme_location’ => ‘secondary’, ‘menu_class’ => ‘nav-menu’, ‘fallback_cb’ => false ) ); ?>
</nav><!– #lower-navigation –>
