‘Function Get Pages” help please :)

Gday,

I am attempting to have a parent page display $more content + link to full content of all children pages.

I found the following code (below) from here Codex -Function Reference/get pages but it doesn’t quite do what I’m after.

I need help adjusting the below code to:

• only output $more content of children pages + title + read more link (at the moment it outputs all content of the child pages)
• only output children pages of the “Gallery” page id=88 (for some reason it is including content of another non related page
• output all children pages of the parent, not just 2.

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

            $count = 0;
			$more = 0;
            foreach($pages as $page)
            {
                $content = $page->post_content;
                if(!$content)
                    continue;
                if($count >= 2)
                    break;
                $count++;
                $content = apply_filters('the_content', $content);
            ?>
                <h3><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h3>
                <?php echo $content ?>
            <?php
            }
        ?>

Help would be greatly appreciated.

Cheers
