Page template pushes sidebar down

Hi everyone,

I’m trying to design a page template so that a list of all the child pages is listed at the end of the page; this list has to be preceeded by a short text which contains the title of the page. The code I’m using is

<p>Text...  <strong><?php
$title = get_the_title($post);
echo $title;
?></strong> more text:</p>
				<ul>
  <?php
  wp_list_pages('sort_column=menu_order&amp;title_li=&amp;child_of='.$post->ID);??>
  </ul>

which seems to work, but it pushes the sidebar down and I don’t know why. Any help would be very appreciated!
