Let me try to elaborate and thanks for the response. We changed "providers" of our credit card services. The old provider and the new provider both use Elavon. So, all I really needed to receive was a new Merchant number. Our merchant ID to log into Virtual Merchant remained the same. Virtual Merchant now has two merchant numbers, an OLD one and the NEW one we want to start using. How do I get Cubecart to request and process through the NEW merchant number through VM? Obviously, its an edit to the gateway settings, but I am not sure what it is. It might be as simple as deleting the OLD merchant number off VM. Suggestions?
