Two queries on same page

This is my second topic about this. The first I thought was working and closed it as resolved. link

What I am trying to do is break the index into two sections. The first displays the most recent post in category 3 and the second section displays the most recent post in categories 5,25,21,26,19,10,27,29, or 24.

I don’t update the second section as much. I have made several posts to category 3 in the last week and they display correctly.

Today I make a post to category 26. It displayed in the first section instead of the second and nothing displayed in the second section.

I am guessing there is some problem with my queries. I took the code from a post I found on the forums here.

<font size="5">Latest Blog Entry</font>
<!-- begin news loop -->
<?php $my_query = new WP_Query('category=3&showposts=1'); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID; ?>

		<div class="post" id="post-<?php the_ID(); ?>">
			<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
			<small>By <?php the_author() ?>  | <?php the_time('F j, Y'); ?> <?php edit_post_link('(edit)'); ?></small>

			<div class="entry">
<?php the_content('Read the rest of this entry &raquo;'); ?>
			</div>

			<p class="postmetadata"><?php the_tags('Tags: ', ', ', '.'); ?> Read more from <?php the_category(', ') ?> | <?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?>

			</div>

<?php endwhile; ?>
<!-- end news loop -->

<font size="5">Latest Story</font>
<!-- begin story loop -->
<?php query_posts('cat=5,25,21,26,19,10,27,29,24&showposts=1'); ?>
<?php while (have_posts()) : the_post();
if( $post->ID == $do_not_duplicate ) continue; ?>

		<div class="post" id="post-<?php the_ID(); ?>">
			<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
			<small>By <?php the_author() ?>  | <?php the_time('F j, Y'); ?> <?php edit_post_link('(edit)'); ?></small>

			<div class="entry">
<?php the_content('Read the rest of this entry &raquo;'); ?>
			</div>

			<p class="postmetadata"><?php the_tags('Tags: ', ', ', '.'); ?> Read more from <?php the_category(', ') ?> | <?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?>

			</div>

  <?php endwhile; ?>
<!-- end story loop -->

Anyone know what I did wrong?
