sorry for the delay in getting back to you on this one, it took a little to find a work around.
I'm not sure of the cause, but to work around the problem, change:
<?php
$bibbieCart->GetContent();
?>
to:
<?php
//$bibbieCart->GetContent();
?>
then change it back after the recordset is added. I will log a bug so we can look into the cause further and fix it for a future release.
