I want my customers to be able to pay by credit card, to do so, I am setting up a contract with Saferpay SIXX. To do so, they obligate me to have a special message to come up, if a person does not agree with the agbs. Currently, it does just change the backgroundcolour, but this seems to be not enough for saferpay sixx. So is it possible to have a short message showing up, saying "You have to accept the AGB's to buy in our shop".
Thanks for your help
