Using ‘query_posts’ to list ‘child_of’ and can’t limit number of posts

Hi,

I am using a plug-in that created an argument ‘child-of’ to list child of a page.

I am using a query_post to get those children and its all good but it doesn’t catch the ‘posts_per_page=’ or ‘showposts=’ arguments. It keeps on displaying all of the subpages. I tried setting my global post per page limit lower but it doesn’t affect this query. Here’s the code i am using to query my posts and display them:

<?php query_posts('static=true&child_of=19&posts_per_page=3&orderby=menu_order&order=ASC'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="derniere" id="post-<?php the_ID(); ?>">
<!-- thumbnail wrapper -->
<div class="thumb main">
<!-- 235150image-covers -->
<?php $image = get_post_meta($post->ID, 'thumbnail', true); ?>
<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><img src="<?php echo $image; ?>" alt="" /></a>
<!-- 235150image end -->

<!-- thumbanil title -->
<div class="thumb-title">
<h2><a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_title() ?></a></h2>
</div>
<!-- thumbanil title end -->

</div></div>
<?php endwhile; ?><?php endif; ?>

If someone has an idea what i could do to limit those posts, I would be jumping up and down like a pogo!

cheers,
Brian
