Custom Fields in Appointments+

Hi,

I can't figure out how to add custom fields to my form when people are confirming their chosen appointment.

Can you please give me some guidance?

I searched the forums.

It said "There is a new add-on called "additional fields", you can enable this in wp-admin > appointments > settings > add-ons." I did this.

Then it says "Once enabled, you can add new fields from the main appointments > settings, you add the fields one at a time, once you've added one field, you can add another field, fields currently can be text or checkbox, and require or non-required."

I don't have this option. Can you help?

FYI I deleted the Appointments lite plugin and then uploaded the Appointments+ plugin.

Cheers
Ian
