need wordpress sub page (child page) help

--------------------------------------------------------------------------------

Ok, so having a small issue with my site.

By default Sublt is showing ALL sub pages of a certain page. Meaning if i have a page named "Dogs" and then there is a sub page of dogs named "Big Dogs" and then a sub page of big dogs named "Golden Retreivers" Currently the sidebar on "Dogs" shows both "Big Dogs" and "Golden retrievers" but i WANT it to just show "Big Dogs" and then you won't see "Golden Retrievers" until you click on the "big Dogs" page. make sense?

The current call for sub-pages in the templates looks like

<div id="child_pages">
<h3>More Pages</h3>
<ul class="icon jump">
<?php foreach ($aSubPages as $page) { echo('<li><a href="' . $page->guid . '">' . $page->post_title . '</a></li>'); } ?> </ul>

</div>

Since i don't know WP or PHP that well, can someone please tell me what to change it to do get the desired functionality? (so only child pages show on a page, not grandchildren). thanks!!!

 

does this help > http://codex.wordpress.org/wp_list_pages

maybe this too > http://wordpress.org/support/topic/89781

 

kind of helped. it made me realize that maybe this is what i really need to change:

<?php

if ($aOptions['show_subpages']) :

global $id;
$aSubPages = get_page_children($id, '');
if (count($aSubPages) > 0) :

?>

just not sure what to change it to. this stuff is a bit confusing for me....
