Я пытаюсь интегрировать Paypal, и я не понимаю все правильно. Когда сайт перенаправляется на Paypal, он показывает веб-страницу (изображение, которое я добавил с этим сообщением).
Пожалуйста, кто-нибудь поможет мне выйти из этого беспорядка, потому что я делаю это впервые.
Пожалуйста, кто-нибудь подскажет, где я могу ошибаться. alt text http://img341.imageshack.us/img341/6920/captureqt.jpg
Я использовал этот класс для интеграции Paypal с моим сайтом. Но не знаю, почему я не получаю нужную вещь.
