"Dynamic To" Mailer Error: You must provide at least one recipient email address.

Hallo and thanks for helping.
I want to use the "Dynamic to" field to send to client a copy of the email.
I setup the Dynamic to field with the field name of the form (email field)
I left blank the normal filed "to" and if I get this error when I send the form:
(it seems that the field "TO" is mandatory"
​

Hi grazianodemaio ,
​
What exactly do you have in the Dynamic To box - it looks as though the element name is Email with a capital E.

Hi Bob, I have Email in the Label and email in the field name, thanks for helping
​

Hi grazianodemaio,
​
That looks correct but it is not what is showing in the Debugger output you posted. Please can you post a link to your form so we can take a quick look.
