This page of archived posts won’t display more than 9 posts. Here is the code —

<?php
/*
Template Name: Talks-Archives
*/
?>

<?php get_header(); ?>

<?php $today2 = (date('Y-m-d H:d:s')); ?>
<?php $today = strtotime($today2); ?>

	<?php query_posts('category_name=talks-seminars');

	$wp_query->is_category = false;
	$wp_query->is_archive = false;
	$wp_query->is_home = false;
	?>

        <div class="post" id="post-<?php the_ID(); ?>">

               <div class="header">
                 <table width="100%"><tr><td>
                 <h2>Talks and Seminars</h2></td>
                 <td> <span class="date"><?php echo date('F jS, Y') ?></span>
                 </td></tr></table>
              </div>

	<ul style="padding-left: 10px">
               	<h3>Archived Talks &amp; Seminars</h3><br />

	<?php while (have_posts()) : the_post(); ?>
                <?php $posttime = strtotime($post->post_date); ?>
                <?php $md_posttime = date("dmy",$posttime); ?>

                <?php if ($posttime < $today) { ?>

		<div class="entry" style="padding-bottom:0;margin-bottom:0" id="post-<?php the_ID(); ?>">

                  <?php if ($md_posttime == $old_posttime) { ?>
		   <p style="margin-left:26px; margin-top:-12px; margin-bottom:7px"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></p>

		<?php } else { ?>

		<li><strong style="font-style:italic;font-size:11px"><?php the_date(); ?></strong><br /><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
	     <?php } ?>
		</div>
                 <?php $old_posttime = date("dmy",$posttime); ?>
	<?php } ?>	

	<?php endwhile; ?>
		</ul>

It makes no sense to me that it won’t display beyond 9 posts, any help greatly appreciated! thanks! vicki
