[Help Wordpress] What is the easiest way to do:

Hello again, I have a problem with php queries of wordpress in your slider.
When I edit a slide in the custom slider (of Royalslider of course) and add php code to list posts from category, such as:

$catquery = new WP_Query( 'cat=1&posts_per_page=2' );
while($catquery->have_posts()) : $catquery->the_post();
?>

• 
  
  
  
  
  

It only writes

have_posts()) : $catquery->the_post(); ?>

This code works perfectly in a widget, but does not work in the royal slider. Any help?
