Catchable fatal error

I am getting this error:
Catchable fatal error: Object of class WP_Post could not be converted to string in /home/public_html/wp-content/themes/Avada-Child-Theme/woocommerce/single-product.php on line 103.
I am using the relationship field type and using this in my template file:

<?php

$values = get_field('field_name');
if($values)
{
	echo '<ul>';

	foreach($values as $value)
	{
		echo '<li>' . $value . '</li>';
	}

	echo '</ul>';
}

// always good to see exactly what you are working with
var_dump($values);

?>

I did a var_dump and this is what I got:
array(1) { [0]=> object(WP_Post)#2711 (24) { [“ID”]=> int(10120) [“post_author”]=> string(1) “6” [“post_date”]=> string(19) “2013-06-06 13:34:05” [“post_date_gmt”]=> string(19) “2013-06-06 17:34:05” [“post_content”]=> string(937) ”

Help appreciated.
