I noticed a problem when activating my store on the FoxyCart web site. I filled in my payment information, but forgot to put in the credit card CVC code and a message displayed that told me that. I then typed the CVC and clicked the confirm button again and still got the message saying the CVC code was missing. I was unable to proceed and had to cancel and start over. It worked when I put the CVC in at the same time as the rest of the payment info.
