How to set Form Limits Based on a Unique Question

Let's suppose you are running a contest and would like to limit unique entries or values in a form. For example, you might want to accept Unique Cell Phone numbers. To accomplish that, follow the steps below:

1. Add a Short Text Entry field (rather than the pre-designed phone field) and label it as Cell Phone.

2. Click on Settings>>Form Settings, and then on the Show More Options button.

3. Scroll down, and choose Cell Phone field from the available options of the Unique Question drop down:

You can even customize the Warning messageYou can find out more details on  regards to Form Warnings.

Form limits based on Unique Questions will work on any input type such as Email fields or plain Text fields.

On the example above, you can even add a Hover Text and a Hint value to indicate if you want only numbers or just separated by a dash, as on this example.

Currently, this feature is available only for drop down selectors and fields which have a single text box. It will not work for Full NamePhone or (Postal) Address because they each consist of multiple text boxes. It also will not work for Text Areas (the tool immediately under the Text Box in the Form Tools menu).

    How Do I prevent a duplicate registration

    This is a GREAT feature! But, you need to get it working for Full Name, Phone Number and (Postal) Addresses so that people can validate submissions.!!

    If I have a submission that needs to be edited and I have a unique question, an edited submission will still be allowed correct?

    We have a booking form with times but teachers would like to block out some of the times en masse.

    Rather than them putting a lot of dummy records in, I tried uploading the required records using the Import CSV. However when I try to add an entry using one of the blocked out times it still allows me.

    How do I convince the system that these times are already booked?

    We would like this to work in Quick Tools "Number" field because we want to also use the minimum and maximum value. But it appears the Unique Question doesn't work with the Number field. Can you make it work with that? We need the flexibility both offer.
