I have just opened a merchant account with Barclays and they have sent me a massive document in order to integrate their payment gateway. I only know a bit about html and flash so I am totally baffeled. Has anyone allready integrated Barclays ePDQ into ZenCart. I am sure that a lot of the stuf they are asking me to do has allready been done by ZenCart and just needs tweeking, the problem is, What Stuff.

Can anyone help me "Please"
Kind regards
Steve
