That’s weird…..

I have the following code:

<?php
  query_posts('showposts=3&cat=15');
  while (have_posts()) : the_post();
    ( Display title, image and some text. )
  endwhile;
?>

This should show 3 posts right? Then why is it showing 2?
I’ve also tried setting it to display 4 posts. It displayes 4 for a while, then sudenly it jus tshows 3…..

You can see the effect here: https://www.norwegianfashion.no. Under the column NYHETER, there are only 2 “boxed” articles. Should be 3….

Here is the entire code

query_posts('showposts=3&cat=15'); ?>
    <h3> Nyheter  </h3>
    <?php while (have_posts()) : the_post();

    	$main_article = get_post_custom_values("main_article");
  	  $related_image_url = get_post_custom_values("related_image");
  	  $related_alternate_image_url = get_post_custom_values("alternative_image");
      $imgTitle = get_post_custom_values("image_title");
      $imgUrl = '';
      $imgHtml = '';    

       //If an alternate image is used, this will be used as thumbnail
      if (!empty($related_alternate_image_url[0]))
         $imgUrl = $related_alternate_image_url[0];
      else
         $imgUrl = $related_image_url[0];

      // Create image URL and add image text if it exsists
      // Identifies if the URL is for an external image or local image

      if (stristr($imgUrl, 'https://') == true){
      	$imgHtml = '<img src="' . $imgUrl .'" alt="' . $imgTitle[0] . '" />';
      }
      else {
      	$imgHtml = '<img src="' . get_option('home') . '/wp-content/uploads' . $imgUrl .'" alt="' . $imgTitle[0] . '" />';
      }

    	//Display all aticles which is not main article
      //Warning! Must manually make sure thre is only one main article, unless the article is to dissappear.
    	if(empty($main_article[0])):

      	echo '<div class="feature">';
    		if(!empty($imgHtml))
    		{
    	  	echo '<a href="' . $permaLink . '">';
    	  	echo $imgHtml;
    	  	echo '</a>';
    	  }

      	echo '<a href="' . get_permalink() . '" class="title">';
        echo the_title(); echo '<br />';
        echo '</a>'; ?>
        <span>(<?php the_time('d.m.y'); ?>) </span>
        <?php
        echo the_content_rss('Les mer','', '', 20);
        echo '<a href="' . get_permalink() . '">Les mer</a>';
        echo '<div class="clearfloat"></div>';
        echo '</div>';
      endif;
    endwhile;
