Special Code Every X Posts

Hello,

Love the plugin, it is one of the most professional options out there. Right now I am trying to have the template display posts, and every say 5 or so posts it displays a script for some advertisement or an “around the web” type box.

The only issue is I can for the life of me not get it to work. If we have anything in the box with a condition it will just not render anything.

I have even tried just adding in code to display text every 5 posts. yet still no dice.

I welcome your help on the matter.

Here is the code right now, and it refuses to render.

<li<?php if (! has_post_thumbnail() ) { echo ' class="no-img"'; } ?>>
   <?php if ( has_post_thumbnail() ) {
      the_post_thumbnail(array(150,150));
   }?>
   <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
   <p class="entry-meta">
       <?php the_time("F d, Y"); ?>
   </p>
   <?php the_excerpt(); ?>
</li>
<?php
  if($alm_current === 6){
   echo "Hello World";
  }
?>
