I do not understand if I can process the field values in a response, then if the response is incorrect or incomplete, can I send an e-mail back to the Responder? I want to indicate in the email the specific fields which are not right in his form. Of course, what I really want is that he can fix his form entry and re-submit. But I don't think that that is possible on FormsCentral.
We don't support such case.
The closest workaround would be to mark some fields as required to help users to fill in all required fields first time.
So, unless I can check field consistency while in the form itself, there is no way for the Responder to fix the response.
Okay, I will study the field checking features in "designing a form" more thoroughly.
