I need to assign a unique Personal Identification Number (PIN) for each submitter of a form (can include letters). We will be using a web form ballot at a convention at which any delegate can use any web-capable device (including a multi-user "kiosk" computer or tablet) to complete a ballot. The PIN will be used to confirm voting status and that only one ballot per delegate is submitted.
Is there a way to facilitate this in a FormsCentral web form?
One way would be to add a calculated field from other form entries.
Another way would be randomly-generated unique text and/or number content for the field.
Is it possible to specify that a form field be unique or otherwise validate field content?
Currently, in FormsCentral we cannot restrict users to submit the form more than once.
You can filter out the duplicate data from the response tab manually but on a real time basis, it's not possible.
