You are creating an ASP.NET application for an online payment service. The
service allows users to pay their bills electronically by using a credit card.
The application includes a payment page named Payment.aspx. This page contains a form
for entering payes, payment amount, and credit card information. When a user needs to
submit a new billing address to a payee, the page form allows the user to provide the new
address information. If the user indicates a change of address,
ProcessAddressChange.aspx page processes the request for a change of address but does
not provide any display information for the user. When the requested processing is
complete. Payment.aspx displays status results to the user.
You need to add a line of code to Payment.aspx to perform the functionality in
ProcessAddressChange.aspx
