Hey Jon,
Just to rule out a couple of things, you say this is outside of the loop so is it not between the following lines?
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<?php // The code is not here? ?>
<?php endwhile; ?>
Also, is the repeater located on the page you’re trying to display it on? Or is it elsewhere?
Cheers, Dan
