How to make such a check in the bot?

Question

Python

I'm writing a bot, and when he clicks on a button, he needs to enter a number and a number from 1 to 5.
Here's how I did it:

def get_number(message):
    try:
        if len(message.text) == 13:
            handle = message.text
            number = handle.split(' ')[0]
            ret = handle.split(' ')[1]
            print(f'{number} + {ret}')
            if int(ret) < int('5'): # тут идет проверка на число от 1 до 5
                bot.send_message(message.chat.id, '<b>✉️началось</b>', parse_mode='HTML')
        if len(message.text) == 14:
            handle = message.text
            number = handle.split(' ')[0]
            ret = handle.split(' ')[1]
            print(f'{number} + {ret}')
            if int(ret) < int('5'):
                bot.send_message(message.chat.id, '<b>✉️началось</b>', parse_mode='HTML')
    except:
        bot.send_message(message.chat.id, '<b>Произошла ошибка!</b>', parse_mode='HTML')

@bot.message_handler(content_types=["text"])
def message_handler(message):
    if message.text == '✉️Начать':
        message = bot.send_message(message.chat.id, '✔️Введите номер в международном формате (без +), а также число от 1 до 5. пример 79999999999 5')
        bot.register_next_step_handler(message, get_number);

    else:
        bot.send_message(message.chat.id, '<b>wtf</b>', parse_mode='HTML')

bot.infinity_polling(True)

But when I enter the text after the message Start, I enter 79999999999 5, but in the end, nothing is written, either in the console or in the TG. help me please
