Comment Problem

Hi, I am working on single.php. I wanted to insert the comments and the add comment form under the post. I have it working, except if gives me the error

Warning: Invalid argument supplied for foreach() in /homepages/7/d299647896/htdocs/wwwsaldef/_WordPress/wp-content/themes/saldef/single.php on line 40

My code:

<?php
/**

 * @subpackage Default_Theme
 */

get_header();
?>

	<div id="content">
    <div id="left_content">

	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

		<!--<div class="navigation">

			<div class="news_content">

				<h1><?php the_title(); ?></h1>
				<br class="clear" />

				<?php the_content(''); ?>

	</div>

	<?php endwhile; else: ?>

		<p>Sorry, no posts matched your criteria.</p>

<?php endif; ?>
</div>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

I am pretty sure its a simple thing like i didnt close an if statement… Help?
