    16 number only

    Asked by Transcendmarketing on October 28, 2016 at 03:59 PM

    Can I set up a fill in for only 16 numbers? no more and no less?

    example: I have account number that must require 16 numbers but some people make a mistake and only fill in 15 sometimes.

    I see that you are using Number for the Account Number field in your form. 

    May I suggest you use a Textbox instead and set an Input Mask?

    This way, your respondents will be forced to enter 16 digits for the account number field. An error will be displayed if they fail to do so.

    I hope this helps. Let us know if you need any further assistance. Thank you.
