the_excerpt question

When I click on “read full story” under my post, it doesn’t show the full post but just give me a black page.

Have a look at my code please:

<?php get_header(); ?>
<!-- BEGIN content -->
<div id="content">
<?php
wp_blogmark();
$temp_query = $wp_query;
query_posts(array('post__in'=>array(dp_settings('featured'))));
if (have_posts()) : the_post();
?>

<?php endif; ?>
<?php include("csidebar.php"); ?>
<!-- BEGIN content content -->
<div id="ccontent">
<h2>Recent Articles</h2>
<?php
$wp_query = $temp_query;
if (have_posts()) :
while (have_posts()) : the_post();
$arc_year = get_the_time('Y');
$arc_month = get_the_time('m');
$arc_day = get_the_time('d');
?>
	<!-- begin post -->
	<div class="post">
	<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
	<p class="details"><a href="<?php echo get_day_link("$arc_year", "$arc_month", "$arc_day"); ?>"><?php the_time('M j, Y') ?></a> | <?php comments_popup_link('No Comments', '1 Comment', '% Comments'); ?></p>
	<?php dp_attachment_image(0, 'thumbnail', 'alt="'.$post->post_title.'"'); ?>
	<?php the_excerpt(); ?>
	<div class="break"></div>
	<a class="readmore" href="<?php the_permalink(); ?>">Read the story &raquo;</a>
	</div>
	<!-- end post -->
<?php endwhile; ?>
<p id="postnav">
	<?php next_posts_link('&laquo; Older Entries'); ?> &nbsp;
	<?php previous_posts_link('Newer Entries &raquo;'); ?>
</p>
<?php else : ?>
<div class="notfound">
	<h2>Not Found</h2>
	<p>Sorry, but you are looking for something that is not here.</p>
</div>
<?php endif; ?>
</div>
<!-- END content content -->
</div>
<!-- END content -->
<?php get_sidebar(); get_footer(); ?>
