When you fill out a registration as an individual, the information is passed to authorize.net net as the billing info and AVS matching is successful. When you fill out a registration as a group, the address info gets passed to authorize.net as the SHIPPING info, and the billing goes in blank. This makes AVS fail, and then the transaction is declined by authorize.net.
Is there away for the fields that are listed as BILLING INFORMATION to actually be sent as billing and not shipping?
