Thanks Eric. I understand that PS3 was not designed with this type of transaction in mind, but never the less, if it can be modified to support Authorizations instead of Sales, I would think that would be of benefit to others too, not just me.
You say the code I am looking for can be found on confirm and pp_confirm....and maybe the checkout page? Can you elaborate please? Is this a big deal, or just a few lines of code. The concept seems simple enough, and PayPal seems to think the changes on the cart end are minor.
Would eCart5 (which I have) be any help with these changes?
