include a side bar menu to the apperance menu

Hello,

I would like to include a side bar menu on the apperance menu in order I can customize it.

I know that I change something on this code but as I don’t know php, I don’t know how.

Thanks very much.

the menu that I want to include is on the client area: https://www.dropbox.com/s/1c6mu9at7dm6axb/fast%20nav.PNG

<!–BEGIN #sidebar .aside–>
<div class=”sidebar” style=”<?php echo $sidebar; ?>; margin-top:10px;”>
<div class=”sidebar-widget”>
<h3 class=”sidebar-title”><?php _e(‘Fast Navigation’, ‘Creativo’); ?></h3>
<div class=”split-line”></div>
<div class=”clr”></div>

<?php if(is_page(‘$post->post_parent’)): ?><?php endif; ?>
<li <?php if(is_page($post->post_parent)): ?>class=”current_page_item”<?php endif; ?>>post_parent); ?>” title=”Back to Parent Page”><?php echo get_the_title($post->post_parent); ?>
<?php
if($post->post_parent)
$children = wp_list_pages(“title_li=&child_of=”.$post->post_parent.”&echo=0″);
else
$children = wp_list_pages(“title_li=&child_of=”.$post->ID.”&echo=0″);
if ($children) {
?>
<?php echo $children; ?>
<?php } ?>
****this is the lines that I tried myself********

<?php function register_my_menu() { register_nav_menu(‘Fast Navigation’,__( ‘Fast Navigation’ ));
}
add_action( ‘init’, ‘register_my_menu’ );<?php } ?>

</div>
