Show View Count in Query/Loop

Hi I’m looking at making the post count appear via my posts page in my query/loop but it doesn’t show and I can’t seem to work out why:

<?php query_posts('posts_per_page=1&orderby=date&order=DESC&cat=-1458'); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <div class="switch">
        <div class="avg_words">
            <a href="<?php the_permalink() ?>">
	        <?php echo the_post_thumbnail('si-images'); ?>
            </a>
        </div>
     <div class="avg_num">
         <span><?php if(function_exists('the_views')) { the_views(); } ?></span>
          <a href="<?php the_permalink() ?>">
	        <?php echo the_post_thumbnail('si-images'); ?>
           </a>
     </div>
  </div>
<?php endwhile; endif; ?>

Any ideas on why this isn’t loading?
