How can we show an error and prevent submission of a value previously submitted on the same form?

Good Morning.

My name is jose, want to know if you can limit a space on the form,

I am creating a database, with personal identification numbers.

What I want is if I do that when I enter a repeated number out an error.

Do you mean that you want to error out and prevent an identification value from being reused?

So for instance if Bob chose personal id # 1040 then Joanna would have to pick anything except that number otherwise it'd show an error message.

Is that what you mean maybe?

I want created a formularie, in i can created a dats base. When I enter the number 2 enbie keep it and if I write again leave me an error when saving

The only way to do that would be to set your form with the unique question form limit.

You can see more about it here: How to set Form Limits Based on a Unique Question

Basically it would show an error when someone enters the same value that was already submitted.

Do note hover Jose that this will not check your own database, but would instead check records on JotForm side in order to confirm if the same should be used or not.

If you however wish that everyone has its unique ID that follows a specific format it might be easier if you use a widget such as Unique ID
