How do I print 4 boxes with 5 links on each

Hello.

I have a problem with listing four boxes with 5 latest links from each category in the index page of my theme. The theme is live at https://videofoto.hiof.no . The problem is that the code I use lists 5 links in total over the four boxes instead of 5 links on each box.

I use the following code…
theme/index.php

<?php 

$boxclass = "list";
$boxname = "<a class='categoryheading video' href='video/'><!--:en-->Video<!--:--><!--:no-->Video<!--:--> &raquo;</a>";
$showposts = "5";
$catnr = "8";

include("module_boxlist.php"); 

$boxclass = "list";
$boxname = "<a class='categoryheading photo' href='photo/'><!--:en-->Photo<!--:--><!--:no-->Foto<!--:--> &raquo;</a>";
$showposts = "5";
$catnr = "5";

include("module_boxlist.php"); 

$boxclass = "list";
$boxname = "<a class='categoryheading sound' href='sound/'><!--:en-->Sound<!--:--><!--:no-->Lyd<!--:--> &raquo;</a>";
$showposts = "5";
$catnr = "7";

include("module_boxlist.php"); 

$boxclass = "list";
$boxname = "<a class='categoryheading article' href='artikkel/'><!--:en-->Articles<!--:--><!--:no-->Artikkel<!--:--> &raquo;</a>";
$showposts = "5";
$catnr = "3";

include("module_boxlist.php"); 

?>

theme/module_boxlist.php

<?php global $more;
$more = 0;
?>
<div class="<?php echo $boxclass; ?>">
					<h4><?php _e($boxname); ?></h4>
					<ul>
						<?php query_posts('showposts=' . $showposts);
	  						while (have_posts()) : the_post();
	  						if (in_category($catnr)):
						?>

						<li class="frontpagelist"><a href="<?php the_permalink(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li>

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

Thanks in advance to good ideas on how to fix the problem.
