One PHP block works, the second doesn’t!

I’m using a pod template with lots of fields to render out my posts. In the markup below (taken from my template), the first <?php echo urlencode( $partner_link_url ); ?> link works, but the second doesn’t, and I can’t for the life of me work out what the problem is! The outputted HTML markup appears to be valid. Anyone have any ideas!?

<?php
$pod = pods( 'partner', get_the_id() );
$partner_link_url = $pod->get_field( 'partner_link' );

// call your taxonomy as a pod because when you extend it, it makes it a pod object
$mytax = pods( 'partner_category' );

$tax_category = $mytax->field( 'partner_category.name' );

// Get terms for post using typical wordpress terms loop
$terms = get_the_terms( $post->ID , 'partner_category' );
// Loop over each item since it's an array
foreach ( $terms as $term ) {
	//do a typical fetch to get your pod fields
	$mytax->fetch( $term->term_id );
	$tax_sidebar_background_colour = $mytax->get_field( 'sidebar_background_colour' );
	$tax_icon = $mytax->get_field( 'icon' );
}
?>
