Page depth not working on function

Hi all,

I’m trying to use get_pages to list pages in a more sophisticated manner than wp_list_pages, however to get the ULs to work properly with the depths then I need to find each page’s depth, however, I created a function to get the page depth but it doesn’t work on the subpages.

This is the function:

function pagedepth($page)
{
	$ancestors = get_post_ancestors($page->ID);
	return count($ancestors);
}

And this is the list pages:

function listpoint($pg)
		{
			echo pagedepth($pg);
			echo '<li><a href="';
			echo get_page_link($pg->ID);
			echo '">';
			echo $pg->post_title;
			echo '</a> ';
			echo get_userdata($pg->post_author)->display_name;
			echo '—';
				if (get_post_custom_values('Character', $pg->ID)==TRUE)
				{
				  $mykey_values = 	get_post_custom_values('Character', $pg->ID);
				  foreach ( $mykey_values as $key => $value )
					{
				    echo $value;
					echo ', ';
				 	}
				}
			echo mysql2date('D, M j, Y H:i a', $pg->post_date);
			echo '</li>';
		}

		function listpages($thepost){
			$pages = get_pages('child_of='.$thepost->ID.'&sort_column=post_date&sort_order=DESC');
			$previousdepth = 0;
			$homedepth = pagedepth($thepost);
			foreach($pages as $page)
			{
				$pagedepth = pagedepth($page);
				if($pagedepth > $previousdepth)
					echo '<ul>';
				while($pagedepth < $previousdepth && count(get_pages('child_of='.$page->ID)) != 0)
					{ echo '</ul>';
					$pagedepth--;
					if($pagedepth = 1)
					break;
					}
				$parent_page = $page->post_parent;
				$content = $page->post_content;
				if(!$content)
					continue;
				$content = apply_filters('the_content', $content);
				listpoint($page);
				$previousdepth = $pagedepth;
			}
	}

Any help would be greatly appreciated.

Thanks.

Cheers,

Luke
