Showing posts in pages

When i use my normal code to show posts where posts should show every thing is blank and
when i tryed this

<div id="content">
<?php if (have_posts()) : the_post(); ?>
<h1><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); // of the page ?></a></h1>
<?php the_content(); // of the page
endif; ?>

	<?php if (is_page('21')) :	// nr of the page you want news in
	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; // restaure pagination
	query_posts("cat=1&paged=$paged"); // nr of the category you want selected in this page
	$more = 0;		// "Read More" in anothe page than Archive thanks to https://www.ads-software.com/support/topic/67173?replies=16
		 if (have_posts()) : while (have_posts()) : the_post();?>
			<div class="entry">
			<h3 class="entrytitle" id="post-<?php the_ID(); ?>"><a href="<?php echo get_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>"><?php the_title(); ?></a></h3>
			<div class="entrybody">
			<p class="entrydate"><?php the_date('','<span>','</span>, '); ?>at <?php the_time(); ?> :</p>
			<?php the_content(); ?>
			</div>
			</div>
	 	<?php endwhile; endif; ?>
		 	<div class="navigation">
			<span class="left"><?php next_posts_link('&laquo; pr&eacute;c&eacute;dentes actus') ?></span>
			<!--<span class="left"><a href="/archives/" title="Acc&eacute;der aux rubriques, tags et archives mensuelles">archives des actus adh&eacute;rents</a></span>-->
			<span class="right"><?php previous_posts_link('actus plus fra&icirc;ches &raquo;') ?></span>
			</div>
	<?php endif; ?>
</div>
<a href="https://www.ads-software.com/support/topic/252598?replies=3">Link</a>

It just shows the title in a permalink of the page?

Any help on how to show posts in pages
