Is there a way for me to add a field so that the customer can get an automatic email or text to the email or phone number they enter?

if I add an email section to my form, how do I get it so that an auto email is sent to that email address?  I tried to set up an auto-response but it does not seem to be working.

I see that it says this:

Send autoresponder email to the person who fills your form.

but I did a form preview and entered my personal email address and no auto response was sent.

I am using my form as an invoice generator so I have added products and a unique ID for a PO.

Email Autoresponder should work in this case. I saw the Recipient email field should be changed to Email as shown in the screenshot below. 

You can also edit the email template in the Email tab. Please refer to the user guide for detailed steps - Setting-up-an-Autoresponder-Email
