Hi,
Im using ijoomla digistore and  pay pal plugin for payment and its working and we bought a new payment and gateway i.e Authorize.Net and we installed and we published it.Our requirement is that when a customer buys a product and he checkouts to buy that product,
there he chooses payments either pay pal or Authorize.Net.But the Authorize.Net that we installed is not working, can any one help me in this issue how to make work the Authorize.net and what is the procedure  and is it possible what i said about my requirement i.e "customer can choose either of payments".
