    jQuery(document).ready(
          $inc = 1;
        function() {
            jQuery('.scroll_container').scrollExtend(
                {   
                    'target': 'div#scroll_items',           
                    'url': 'components/com_a_main_search/more_content.php?limit='+$inc, 
                    'newElementClass': 'list_item more_content'
