I have the following in themename/piklist/parts/media/:

<?php
/*
Title: Cycle Link
Description: The page for the image to link to in the cycle.
*/

piklist('field', array(
	'type'	=> 'text',
	'field'	=> 'url',
	'label'	=> 'Link'
));

?>

But it displays like this:

I assume the field is supposed to be below the title and description.
