brwalker - this does not need turned on. It will show on individual registrations where authorize.net or Echeck is the payment type being used. This gives the ability to supply different billing information than the registrant details. There is a checkbox that will auto-fill the billing info page if it IS the same as the registrant. This was added in a recent release... I'd have to look to see which one
This feature would be useful when other payment methods are used. In our situations the contact details for the registration is almost always the same as one of the group members.

I am having the same problem "same as registrant" isn't populating. I am running authorize.net as test. Will it work properly after I have set up my account with authorize.net? and do you know what you did to fix your problem!!!
