AbleCommerce Shopping Cart Software

Thanks for the tip. I looked at that page many times. I do seem to be doing the difficult route (which to me seems the easy way, but that's my novice ignorance). I would be satisfied to be able to display the checkout button with the proper post form so I could start sending payments to the gateway....

I am looking for the starting point in the code for the process of developing a payment gateway. I have the code set up and I can get the payment gateway to show up in the list on the ablecommerce site, but I do not have the special knowledge that will push me over the top to get the payment gateway...
