Hi, I'm very new to using Zen Cart. I want to set up PayPal as a form of taking payments on my website but I don't know which of the 4 set ups to use. All I want to do is have people purchase on my site, spit out a receipt with the title of the items they are purchasing and then ship the items.

What is the difference between the 4?

And how do I modify the receipt to read what they are purchasing?

Thanks in advance for your help.
