Hi @EugeneNyawara

This is a great question, and one which can be achieved by reading about querying posts via a sub field value here:
http://www.advancedcustomfields.com/resources/how-to/how-to-query-posts-filtered-by-custom-field-values/#example-5

I have done some copy / paste and put together a template for you. Just replace {$repeater_field_name} with your repeater field name, and {$sub_field_name} with your sub field name, and it should work! Fingers crossed:

<?php 
 
// custom filter to replace '=' with 'LIKE'
function my_posts_where( $where )
{
	$where = str_replace("meta_key = '{$repeater_field_name}_%_{$sub_field_name}'", "meta_key LIKE '{$repeater_field_name}_%_{$sub_field_name}'", $where);
 
	return $where;
}
 
add_filter('posts_where', 'my_posts_where');
 
// args
$args = array(
	'post_type'	=> 'whose-posts-we-want-to-display',
	'meta_query' => array(
		array(
			'key' => '{$repeater_field_name}_%_{$sub_field_name}',
			'value' => '"' . get_the_ID() . '"',
			'compare' => 'LIKE'
		)
	)
);
 
// get results
$the_query = new WP_Query( $args );
 
// The Loop
?>
<?php if( $the_query->have_posts() ): ?>
	<ul>
	<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
		<li>
			<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
		</li>
	<?php endwhile; ?>
	</ul>
<?php endif; ?>
 
<?php wp_reset_query();  // Restore global post data stomped by the_post(). ?>

Thanks
