And the syle.css below

</div>

<?php
    if (function_exists('wp_nav_menu') && get_option('gpp_wp_menu')=='true' ) {
        wp_nav_menu( 'sort_column=menu_order&menu_class=sf-menu&theme_location=main-menu' );
    } else {
        include (TEMPLATEPATH . '/nav.php');
    }

<div><?php wp_nav_menu( 'sort_column=menu_order&menu_menu_class=second-menu&theme_location=second-menu' ); ?></div>
<div class="clear"></div>
