Hello. I have installed appointments+ on a client's barbershop web site which has 2 service providers. They each have different PayPal accounts, so I entered both emails in the "PayPal Merchant E-mail" field in settings separated by a comma which I now know is wrong. When they attempt to book themselves to test, PayPal gives an error and just shows the two emails I entered. Also, is there anything else I need to set up or enter to make sure the PayPal process works? I didn't see anything in the instructions about it. Can someone please let me know how I can get this up and working? Thanks in advance for any help.
