So I am using paypal standard. I was able to do another test payment with a different credit card on a different computer and the order was able to be processed, so I'm not sure what the problem is with the other credit card. Maybe it was just a credit card problem.
However I do have a new problem. On the test payment that went through, the sizing information that the customer has to enter into the HEIGHT and WIDTH fields did NOT show up on the receipt. The only information that showed up on the paypal receipt was the description and item number and very little information about the buyer. Can the ecart details be attached to the receipt or emailed to us? Also, when a purchase is made, can ecart have a notification email sent with all the information?
