Trouble listing page title and listing children

Hi all –

I’m having a bit of a problem, and have absolutely no clue why.

If I use

<?php $current_page_id = $wp_query->post->ID;
            wp_list_pages("title_li=&child_of=$current_page_id&depth=1"); ?>
            </ul>

It lists the children of a page with no problem.

I’ve been trying to add a link to the parent above this.

If I try many of the codes suggestions, like this:

<?php
    if(!$post->post_parent){
         $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0&depth=1");
    }else{
	  if($post->ancestors){
		$ancestors = array_reverse($post->ancestors, true);
		foreach($ancestors as $ancestor){
			$ancestor = wp_list_pages("title_li=&child_of=".$ancestor."&echo=0&depth=1");
			echo "<ul>";
			echo $ancestor;
			echo "</ul>";
		}
		$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0&depth=1");
	}
}
if ($children) {
 	echo "<ul>";
 	echo $children;
 	echo "</ul>";
}
?>

It pulls nothing.

I’ve also tried using <?php echo $post->post_title; ?>, and am getting the last blog post…which isn’t even on the page.

Any thoughts? TIA!
