here is the code of the navbar

<div id="nav" class="fix">

<ul class="fix dropdown">

<li class="page_item navfirst">

 

<a class="home" href="<?php echo get_settings('home'); ?>/" title="<?php _e('Home',TDOMAIN);?>" style="background-image: url('<?php e_pagelines('nav_home_image', THEME_IMAGES.'/home-icon-trans.png');?>');">

<?php _e('Home',TDOMAIN);?>

</a>

</li>

<?php

$frontpage_id = get_option('page_on_front');

if($bbpress_forum && pagelinesforum('exclude_pages')){ $forum_exclude = ','.pagelinesforum('exclude_pages');}

else{ $forum_exclude = '';}

wp_list_pages('exclude='.$frontpage_id.$forum_exclude.'&depth=3&title_li=');?>

</ul>

<?php if(!pagelines('hidesearch')):?>

<?php include (THEME_LIB . '/_searchform.php'); ?>

<?php endif;?>

</div><!-- /nav -->
