I have hired a freelancer to create CiviCRM Sign-Up form featuring Tell-A-Friend and validation email.
Using CiviCRM contact Caldera Processor, he created the form shown below but has an integration problem - is not able to map created custom fields "Province" and "Municipality" into CiviCRM's standard fields "State/Province" and "City".
He is not able to use the standard fields as they do not allow him to have 2 pull-down menus (Province and Municipality – see picture below) and other features (Tell-A-Friend and verification email). Your comments and suggestions would be greatly appreciated.
[Note: Selecting a Province immediately populates the Municipality field.]
Environment: WordPress 5.2.2 and CiviCRM 5.15.1 hosted at AWS.
