Installing Authorize [dot] net: Stuck in the middle?

[Tintarella]

The Goal

Getting the module to work with prestashop el pronto

 

The Problem

In cart, authorize module shows. However, when entering the test account information from Authorize.net into the in-test selected module, Prestashop decides to throw me back to the top of the cart.

 

The Solution

I hope you can provide it. Thanks in advance!
