Custom questions allow you to ask important questions of your customers ahead of class, and give your teachers a heads up about the answers ahead of the start time.
To set this up, locate a class and use the dropdown menu to its right to edit it.
Scroll to the bottom section titled Additional Settings > under Custom Questions click Add Question.
Type it here and Save. Choose whether to apply these changes to the entire series (if this is a series).
Customers will now see this field in red at checkout.
Teachers viewing the class details page will see the sign up list now contains the customer's answer.
