why don't i recieve an autoresponder e-mail while I fullfill my form?

Hello,

I'd like that if someone fullfill my form, he'll recieve an autoresponder e-mail.
I add it to te setting but nothing happens.
I don't understand. Do you?

It is not working because you are not assigning an email field type as the recipient. Please make sure to use an email field:
