However, any existing custom fields in CRM that are added to an Event Ticket, Registration, or Add-on will be queryable and reportable in Virtuous. To do this, in your ticket, select Add Question button near the bottom.
You'll then have the option to either add a New Event Question or Existing Custom Field. If you are looking to Query or Report on this data in the future, you'll want to select the Custom Field option. Note: if you are creating a Custom Field in Settings to put in your ticket registration, use a Contact Individual Custom Field type.
Okay, but how do I Query on this?
To find all of the data from your Custom Field, you'll want to create a Query with the type that matches your Custom Field type--in this case an Individual Query. For the first field, you'll search the name of your Custom Tag and use the operator to find the criteria you are looking for.
