prev & next usage for categories

I been trying to get my prev/next buttons to work but only within a specfic catergoty… Haven’t had the luck I hoped for… Here’s the way I am using my code…what am I doing wrong?

<?php query_posts(‘cat=14&showposts=1’); if (have_posts()) : while (have_posts()) : the_post();?>

<div class=”navigation”>
<div class=”alignleft”><?php previous_post_link(‘%link’, ‘Previous in category’, TRUE); ?></div>
<div class=”alignright”><?php next_post_link(‘%link’, ‘Next post in category’, TRUE); ?></div>
</div>

<div class=”post”>
<h2 id=”post-<?php the_ID(); ?>”><?php the_title();?></h2>
<div class=”entrytext”>
<?php the_content(‘<p class=”serif”>Read the rest of this page ?</p>’); ?>
</div>
</div>

As you can see I am only wanting to show one post in this catergory and use the prev/next to get to the next post… PLEASE HELP!!!!!!!!!!!
