First Data (linkpoint) remote checkout
First Data requires the following info from my eCart 5 confirm page: "chargetotal" - "mode" - "storename" in order to process sale - but also allows "subtotal", "tax" and "shipping" info, which my customer wants to see when logging in to bank terminal for sales purposes. When I bind (hidden fields) the subtotal, tax and shipping to confirm page and test I get First Data error "Chargetotal does not equal subtotal, tax, and shipping." I'm not using a database, only static product so I need the bank to provide this info for the owner. I am following the bank's manual but not sure if I'm binding it correctly. Everything works fine until I add these extra fields. Any help would be appreciated. Thanks!
