We have setup a payment gateway using Authorize.net. After the user fills up the Credit Card details, a validation process occurs. When the information is wrong, then the validation redirects to a transact.dll page with this link: https://test.authorize.net/gateway/transact.dll. The screenshot of the page has been attached herewith.
I would like the error message in that page to appear in my website, but I am not able to do that in any way. Can you please help?
