Display child's custom fields on parent page

Hi all,

I have a page called “training” with 7 child pages. On the training page I display a list of these child pages as some kind of overview. Apart from the title of and link to the children, I would like to display the content of the custom “description” field I’ve created on the child pages.

I use this code:

<?php
	$mypages = get_pages('child_of='.$post->ID.'&sort_column=post_date&sort_order=asc');

	foreach($mypages as $page)
	{
		$content = $page->post_content;
		if(!$content) // Check for empty page
			continue;

		$content = apply_filters('the_content', $content);
	?>
		<div class="traject">
        <h3><?php echo $page->post_title ?></h3>
       	<p><?php echo get_post_custom_values('description', $page->ID) ?></p>
        <p><a href="<?php echo get_page_link($page->ID) ?>" class="button"><span>meer info</span></a></p>
        </div>
	<?php } ?>

The title and link are displayed, but no custom description field. How can I fix this problem?

Thanks in advance for your help.
