 * I have 2 category (parent and child) with one template for both. I want to use
   query_posts for pagination. I’m use posts_per_page for limit posts on page. All
   work’s fine except one things – **I cant see child category without parent**.
   If I dont use query_posts all works fine but I cant limit posts on page.
 * My code before loop.
 *     ```
       <?php
           $limit = 6;
           $catid = 4,6;
           $catid = strpos( $catid , ',' ) ? explode( ',' , $catid ) : array( (int) $catid );
           $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
           query_posts(array('category__in'=>$catid,'posts_per_page'=>$limit,'paged'=>$paged));
           $wp_query->is_archive = true; $wp_query->is_home = false;
           ?>
       ```
   
 * Please help me understand!

           query_posts('showposts=' . $limit . '&paged=' . $paged . '&cat=' . $catid);
