    Can you set a minimum size on a form value as well as a maximum?

    Asked by licc on December 13, 2012 at 06:49 AM

    I am collecting a mobile number on a form, and would like to make sure that people input the right number of digits. I've set a maximum value on the field to 11, but would also like to set a minimum value as 11 to prevent people from submitting a form with an incorrect number.

    Is this possible?

    Hi Gemma,

    Unfortunately, there's no option in Jotform to set a minimum lenght in a field. I will try to forward this to our developers and hopefully, they will consider this for future releases. No guaranted ETA for this.
