On an event registration form, you notice the fields populate or do not populate under billing information. You want to know what is prompting this and how you can choose whether the billing information is populated or not populated.
The Billing Information populating on an event registration form is determined by the "User this as my billing information" checkbox for the registrant information. This box is marked by default. If the box is left marked, the information specified for the registrant will display on the billing information. If the box is unmarked, the billing information will not populate with card holder or address information.
