In the program's merchants interface: { Note : Use The Variable Names Provided By Your Cart or Merchant Account. These Are The Variables Passed Back By Your Shopping Cart Or Merchant Account. Only Enter The Variable Name Itself - Exclude Everything Around The Name. Order Amount Variable Name * Order Id Variable Name* } How do the track code work? where to put it? how to know/test whether the code was installed correctly, is the test done by program automatically or by admin manually? Sorry for the noob's question
