Thanks for that Dave,
In the past I've used Cartweaver but I have one client who previouly had an ecommerce system done with Shopfactory. With all this new PCI it appears that they have had to stop using their existing global charge system to enable PGP.
Problem is that to carry on using the existing web site the client would have to have their own full copy of the program or I'll need to implement a third party PGP system.
Just looking into the whys and wheres although (arn't clients wonderful) I was only called about it yesterday and it all happens today!
thanks for the help
