Редактировать: я решил проблему.Радио-поле в Child1Form вызывало проблемы.

Исходное сообщение: эта ошибка возникает, когда я выбираю кнопку «следующий этап» в файле stage_one_complete.В идеале нажатие этой кнопки вернет HTML-страницу ChildSignUp.У меня была такая же ошибка ранее, когда я пытался использовать команду URL перенаправления.
