<?php
global $notfound;
if (is_page() and ($notfound != ‘1′)) {
$current_page = $post->ID;
while($current_page) {
$page_query = $wpdb->get_row("SELECT ID, post_title, post_status, post_parent FROM $wpdb->posts WHERE ID = ‘$current_page’");
$current_page = $page_query->post_parent;
}
$parent_id = $page_query->ID;
$parent_title = $page_query->post_title;

// if ($wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = ‘$parent_id’ AND post_status != ‘attachment’")) {
if ($wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = ‘$parent_id’ AND post_type != ‘attachment’")) {
?>

<ul>
<?php wp_list_pages(’sort_column=menu_order&title_li=&child_of=’. $parent_id); ?>
</ul>
<?php } } ?>

This would go anywhere you wanted subpages to show up.

If you want it in your sidebar, but only wanted it to show on a page, you’d use these conditional tags:
is_page()

The new design looks great btw. I’m jealous now. LOL
