Using WP-PostRatings Outside WordPress

I have a WordPress site and a mobile page. The mobile page is it’s own index.php file and design, and doesn’t call to WordPress at all.

I am attempting to insert the WP-PostRatings as my only WordPress element to this mobile page, but am having some difficulty.

Firstly I put the following code in my mobile index.php I am working in to load WordPress

<?php
include('../wp-load.php');
?>

And then I insert WP-PostRatings based off shortcode.

I see the stars appear.. but they are broken / inactive and not reflecting any ratings or data.

I also get the following errors

current_rating is not defined
ratings_off is not defined

Only if I include code to get_header() and get_footer() (I think maybe just the footer), they work.

The issue is.. I don’t want my WordPress footer, or header on my mobile site. It’s supposed to stand on its own.

Any help on being able to insert WP-PostRatings without the WordPress footer (or header)? Thanks.
