What function would I use to combine two text boxes and add a comma? I’d like to give the applicant the option to add up to 3 email addresses. I think the best way is to create a hidden field, give the applicant 3 text boxes, combine them with a behavior separated by a comma, and use the hidden field to send the notification.
Use a Set Field with a formula to combine values into a hidden field. Separate the values with semi-colons (no spaces). Create a role and make the hidden field the owner of the role. Send the notification to the role.
