I am trying to add a field for social security number in my form and created three fields. I want each field to only allow a limited number of digits and the length validation option is not working. I have a field for three digits then one for two digits and then one for four digits. But it is not stopping the user from putting in more digits than required. I also would like the user to go immediately to the next field after putting in the first three digits. How can I do this?
