ecart checkout with authorize.net
I first tried to select remote processing with the checkout wizard and I just get an error message 103 from authorize.net. I called authorize.net support and they indicate that I should be using AIM with a shopping cart.
I change to AIM, and now when I press the Submit Order button on the Confirm page, I just get a blank web page. It still indicates it is on the confirm page in the Web address, and it says done at the bottom.
