Fetching content on two different pages

Hi, I have two pages that uses the same method to pull data from the perch database. In r.php and y.php the code looks like:

$linkarray = perch_content_custom('Link Builder', array(
  'filter'=>'campaign.url_id',
  'match'=>'eq',
  'value'=>$uniqueurl,
  'skip-template' => 'true',
  'raw' => 'true'
  ));

The code in y.php is identical. For some reason, the content is fetched in r.php but not in y.php. I use the print_r $linkarray function and the array is populated in r.php, but not in y.php. Could you please tell me what I am doing wrong here, and how to fetch the same array in two different php pages? BTW= the query string is grabbed by $uniqueurl is also identical.

Thank you.
