The "Linkpoint Order ID" is blank when viewing an order

Line 26 of includes/modules/payment/linkpoint_api/linkpoint_api_admin_notification.php should be changed to read:

$output .= $lp_api->fields['lp_trans_num']."\n";

Instead of:

$output .= $lp_api->fields['lp_order_id']."\n";

as lp_order_id doesn't exist as a column in the linkpoint_api table
