I have helped install the Appointments+ on a clients site, (actually its a local government home owners association site). The only use of the Appointment is to schedule the Clubhouse.
There is NO charge for making a reservation for the club house, and it can only be reserved by the calendar day. No specific times during the day. Just by the day.
If you visit this page (a test page) http://www.nwhcmud19.org/make-an-appointment/?preview=true&preview_id=90&preview_nonce=0f3983342a&app_service_id=1
It shows, for some reason, two times 9:00am & 9:00pm as two separate times that you can reserve the Club house. So there should be only one "time" as its a all day rental (not sure what time to show).
We have the Time base (minutes) set to 720 (24hrs) to reflect all day rental, and the Additional Time base (minutes) is also set to 720.
I have made a screen shot of Appointments > Settings > Tabs
So you can see how things are set up.
Can you let us know what we are doing wrong?
Thanks for the help!
