How can I prevent the form being submitted unless the user fills out a field with the right answer?

Hello,

Can I limit the possible answers for a field in jot form so that only individuals that posses the right answer for say a number firld or a name field will be allowed to submit the form?

Hello, if your aim is to only allow a user/respondent to submit the form IF AND ONLY IF their response exactly matches a "right answer" then you may use Conditions to achieve that.

Have a look at this quick demo form I came up with: https://form.jotform.com/63565923983975

(test123 is the right answer that the Textbox requires)

The idea here is that they won't be able to submit the form if they don't know the needed response (or the right answer) for the Textbox Field.

Here's how the Condition was setup:
