Is it possible for the echo statement to not display if there is nothing in the custom field in the admin?
<?php
$hometown_port = types_render_field("hometown_port", array("raw"=>"false","separator"=>", "));
echo '<li><span class="descHead2">Hometown:</span> '.$hometown_port. '</li>' ;
?>
The word Hometown: appears even if there is nothing added to the field.
