 * Hi,
 * I followed this instructions and I could avoid the duplicate posts, but the matter
   is that I only display 3 posts on the differents colums… You’ll see “Secundaria”
   in blank.
 * How can I put posts_per_page=3 to show the last 3 post, but not duplicated, the
   previous ones, do you understand?
 * I hope you can help me.

 * A fragment of my code:
 *     ```
       <ul>
       				<!-- NOVEDADES SECUNDARIA -->
       				<?php query_posts('cat=1,-3,-4,-102,-100,-111&order=DESC&posts_per_page=3'); if ( have_posts() ) : while ( have_posts() ) : the_post();  if (!in_array($post->ID, $ids)) { ?>
       				<li id="gradeNews-<?php the_ID(); ?>">
       					<div class="postImage">
       						<a href="<?php the_permalink(); ?>"><?php echo get_post_image('thumbnail','','default-thumb'); ?></a>
       					</div>
       					<div class="postInfo">
       						<div class="postTitle">
       							<h4><a href="<?php the_permalink(); ?>" title="Link permanente a <?php the_title_attribute(); ?>"><?php short_title('','…',true, '35'); ?></a></h4>
       							<p class="postMeta"><?php the_time('j F, Y'); ?></p>
       						</div>
       					</div>
       				</li>
       				<?php } endwhile; else: ?>
       				<li><em>No hay noticias en Secundaria!</em></li>
       				<?php endif; ?>
       				<?php wp_reset_query();?>
       			</ul>
       ```
   
 * Thanks you!

 * So you want to show the latest 3 posts that are in category id 1 and exclude 
   posts from the former loops ($ids)?
    try:
 *     ```
       <?php
       $args= array(
       'cat' => 1,
       'posts_per_page' => '3',
       'post__not_in' => $ids,
       );
       query_posts($args);
       ?>
       ```

   I’m receiving this message: Warning: urldecode() expects parameter 1 to be string,
   array given in /home/firk/mysite/wp-includes/query.php on line 1737 (this also
   happens with ” in ‘posts_per_page’ = ‘3’)
