Paypal Express Checkout Несколько позиций после оформления заказа

В настоящее время я использую Paypal Express Checkout, и у меня есть несколько позиций, входящих в заказ. Эти предметы успешно поступают в Paypal и отображаются индивидуально в счете. Как только клиент возвращается на мой веб-сайт, клиент возвращается через страницу обработки, которая помещает товары в базу данных, но вместо того, чтобы перечислять отдельные товары с их индивидуальными ценами, я получаю только один товар и общую цену.

$InsuranceCost      = 0.00;  //shipping insurance cost for this order.

$ShippinCost        = 0.00; //Although you may change the value later, try to pass in a shipping amount that is reasonably accurate.
