More tag not working in custom page template

Hi, All
Anyone out there know why when I add the More tag on this custom page that I made to display one particular category (Articles) it doesn’t work?
When I changed it to the_excerpt it showed just an excerpt, but no go with the More tag.
Thanks in advance.

<?php
/*
Template Name: Articles
*/
?>

<?php get_header(); ?>
<?php get_sidebar(); ?>
<div id="content">

<?php query_posts('category_name=Articles&showposts=10'); ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); if( $post->ID == $do_not_duplicate ) continue; update_post_caches($posts); ?>
<div class="post" id="post-<?php the_ID(); ?>">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>

<?php the_content('Continue Reading...'); ?>
<div class="post-details"> <h3>Posted in <?php the_category(' and ',''); ?> on <?php the_time('F jS, Y') ?> at <?php the_time() ?> by <?php the_author_posts_link(); ?>. </p><a href="<?php the_permalink() ?>#comments"><?php comments_number('Add a comment','1 comment','% comments'); ?></a></h3>
</div>
</div>
<?php comments_template(); ?><?php endwhile; ?><?php else : ?><div class="post" id="post-<?php the_ID(); ?>">
<h2>Nothing to see here</h2>
