Не получается подключить free kassa

Когда режим интеграции с робокасой включен пишет ошибку - Неверная электронная подпись#1 (но сумму цепляет)

Когда режим интеграции отключен (ставлю нет) пишет ошибку - сумма платежа указана неверно (сумму не цепляет)

В чем косяк не знаю. Я уже голову сломала.:confused: Помогите все настроить пожалуйстоооо.

Есть три файла
