Я пытаюсь собрать несколько значений, введенных пользователем в элементы управления NumericEditField, и сохранить их, чтобы использовать их позже в вычислении, результат которого будет представлен обратно.
Кажется, я могу хранить переменные, но не могу получить к ним доступ позже. Каждая из переменных считается закрытой, потому что именно там я должен добавить обратные вызовы. Я попытался добавить все переменные в публичную часть в начале, но это не сработало.
Вот код:
