Child Pages Only

Hi there.

I’m looking for working solution to menu child pages only. Probably self explanatory, but what I am trying to do is to have my “left hand site menu” with child pages of current page. Also I need this menu to appear in any of those pages.

I googled around, got to this, but this solutions don’t seem to work.

This solution seem to be closest what I need although it is only displaying pages on current parent one.

<ul>
  <?php
  global $id;
  wp_list_pages("title_li=&child_of=$id&show_date=modified
  &date_format=$date_format"); ?>
</ul>

Thank you for your help in advance.
