How to add last 3 posts on pages?

I would like to add the last 3 posts from a certain category on all pages from my blog. The problem is that I want to add them BEFORE the content and I get an error. My current code is:

<div id ="box" here should be the last 3 posts>
<?php query_posts('cat=2&showposts=3'); ?>
	   <?php while (have_posts()) : the_post(); ?>
       <h2> <a  href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>

		<div class="entry">
			<?php the_content_limit(200); ?> <br />
			<?php endwhile;?>
	<div class="clear"></div></div> </div> </div> </div> 

	<div id="contentbox" here should be the content of the page>
      <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

      <div class="entry">
        <?php the_content('Read more...'); ?>
        <div class="clear"></div>  </div>

      <?php endwhile; else: ?>
      <?php endif; ?>

What I’m doing wrong there? ??
