    Make at least one of several phone number fields required?

    Asked by billj on June 26, 2015 at 12:43 PM
    For my own entry onto the feature wish-list I would ask for the capability of making at least one of several phone number fields required. For example; on a form that asks the user to list a home, work or cell phone number. At least one of the three must contain data before the submission is allowed to complete.

    For this, I believe you can use the Conditional logic, you can learn more about it here: http://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic. You can set the form fields to require depending on the set of rules you have.

    Here's a sample form: Here's a sample form: http://form.jotformpro.com/form/51765155382964?

    I hope that helps. You can do more advance actions using conditional logic. 

    Do let us know if you need more information on this.

    Thank you.
