Get post field using Relationship field

Hi all

Another realtionship question sorry

I have a custom post type for testimonials.

The custom post has a testimonial_image, testimonial_text and testimonial_link, that are also CFS fields

I’m using a relationship field ‘the_testimonial’ to select one of the testimonial posts on the home page.

This is all working and I can select a post and echo the title of this post.

<?php

	$values = $cfs->get('the_testimonial');

	foreach ($values as $post_id) {

		echo '<div class="well">';

	    $the_post = get_post($post_id);

	    echo '<h2>' .$the_post->post_title. '</h2>';

	    echo '<p>'. $the_post-> get('testimonial_text').'</p>';

	    echo '</div>';
	}

?>

How can I display the other fields fron the testimonial, like the testimonial_text, testimonial_text and testimonial_link.
