What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If I'm understanding your question correctly, so your condition will be based on the answer given by the user, such as from options of giving numbers 1-9, they can only enter such value once and they shall be prevented from entering the same value on a different question.
Unfortunately, I could not find a solution on how to make this happen within JotForm's limits. I'm theorizing however that this can be possible when you get your form's full HTML source code, place the code on a web page and modify the code there to run such look-up/validation.
If I misunderstood your question or you would like to proceed with this idea, please let us know.
