Power Gallery/Power CMS Database Integratiion

Hi Guys - Am in the middle of the database integration of PowerGallery/PowerCMS and HTMLeditor. I placed the WA_evaluate file in the site root and moved to step two. On the page where I wanted to place PowerGallery, the instructions stated that I should look for the database binding "<?php echo $row_WADAProducts["ProductLongDesc"]; ?>".
The only thing that I found on the page was
<?php
$pg_id = '1';
$pg_theme = 'light';
include('/var/www/vhosts/shadowsnetwork.com/httpdocs/gallery/galleries/grid_lightbox/index.php');
?>

So what am I missing here?

Also, putting the WA_evaluate file in the site root - is this location better than putting it in the PowerGallery folder?
