Require Payment = Yes, breaks appointments +

For my appointments page: http://fixxed.com/test/neh/schedule-an-appointment/

If I have Payment Required set to yes, 2 things happen. No Paypal option/button appears, no confirmation message or emails sent to admin or client. There will be the attempted appointment sitting in the Pending Appointments in the admin.

Here's what I have:
[app_service_providers] [app_services autorefresh="1"]
[app_monthly_schedule][app_monthly_schedule add="1"]
[app_pagination step="2" month="1"]
[app_login]
[app_confirmation]
[app_paypal]
