Hey this henok my payment method does not work can you help me please

Hello henok147,

You'll want to be sure the payment method you're adding is valid in your region which might explain why it's not working. The link you posted from has a list you'll want to look through based on your region: Payment methods that you can use with your Apple ID - Apple Support

You may also want to check with your financial institution to make sure there aren't any issues with adding your payment method to Apple services.

Otherwise, let us know the exact issues you're having when you try adding the payment method.

Enjoy your day.
