Help...RMA Return System

[AnnieChrist]

I took the time to convert the contribute and I seem not to be able to over come a problem in admin/orders.php. The page is blank but does not have an error. If anyone has installed or knows what's wrong please reply!
below is the code I am having trouble with.

//BEGIN RMA MODULE
$returns_check_query = tep_db_query("SELECT r.rma_value, rp.products_id FROM " . TABLE_RETURNS . " r, " .

TABLE_RETURNS_PRODUCTS_DATA . " rp where r.returns_id = rp.returns_id and r.order_id = '" . $oID . "' and rp.products_id = '" . $order->products[$i]['id'] . "'

");
if (!tep_db_num_rows($returns_check_query)){

if ($order->products[$i]['return'] != '1') {
$return_link = '<a href="' . tep_href_link(FILENAME_RETURNS, 'order_id=' . $oID . '&products_id=' . ($order->products[$i]['id']), 'NONSSL') . '"><u>' .

'<font color="818180">Schedule Return</font>' .'</a></u>';
}
// Don't show Return link if order is still pending or processing
// You can change this or comment it out as best fits your store configuration
if (($orders_status == '1') OR ($orders_status == '2') ) {
$return_link = '0';
}
} else {
$returns = tep_db_fetch_array($returns_check_query);
$return_link = '<a href=' . tep_href_link(FILENAME_RETURNS, 'cID=' . $returns['rma_value']) . '><font color=red><b><i>Returns</b></i></font></a>';
}
//END RMA MODULE
