вот код для моего основного файла функция градиента взята из файла фона, код для определения полей ввода отмечен полями # ввода для моих значений с обеих сторон. Мне нужны поля ввода для ввода, а затем, когда нажимаются вертикальные/горизонтальные кнопки, рисуется градиент(мой код градиента уже написан в функции и работает правильно).

выход: мне кажется, что цветовые линии начала/остановки не получают ввода, и я не могу понять, как заставить это работать.
