I am building a form using Solspace Freeform, and we have two fields for telephone numbers - one for landline and one for mobile/cell.
Is it possible for me to make one or other of these fields required? I.E. If the user fills out landline but not mobile the form will submit, if the user fills out mobile but not landline the form will submit, but if the user doesn't fill out either then the form will return an error?
Thanks in advance!
