    Based on what you have mentioned, I believe that you are looking for the mask property to accept only 8 numbers in a field, no more and no less.

    I would however like to confirm this from you if possible and if so we would be happy to assist you in setting it all up.

    It would also be useful if you can give us a link to your jotform to see which fields you are using.

    You can click on the field in question, and set the Input Mask on it. Make sure to click on the 'Fill Mask Validation', so it will ask for the exact amount of symbols.

    Thank you.
