Just looking into this a bit deeper. On this page from worldpay custa.html
there is a line
"To insert merchant-defined text into the Shopper Confirmation Email with the Payment Page Editor, you will need to include a custom parameter, with its value, in the order details submission and then enable its display via the Payment Page Editor, as described below."
1. What parameters are sent to worldpay from the confirm page?
2. I think I could pacify the client by just adding as an extra, the product description from the ProductLongDesc column. Is this parmeter sent, or if not, as stated in the line from worldpay, can it be sent as a "custom parameter, with its value, in the order details submission and then enable its display via the Payment Page Editor"
Fingers crossed!
