can "Email" unique without duplicate when submission

[bygod@139.com]

Dear Sir,

I Set Up the form , which including "Email" fields.

Can I make Email Data Unique without duplicate when submission.

For Example:
Account A firstly submit "bygod@139.com" to the Field Email successfully.
When Account B or other Accounts secondly submit the same "bygod@139.com" to the same field Email, the results must be Failed, as already have bygod@139.com.

Can you tell me how to fix, so that can make this function become true?

Yours
Jacky

Hi Jacky,

Thanks for the post!

Yes, you can detect for uniqueness with a particular submission, but only using the API. Take a look at the following tutorial:
