How do I use the cancel link to cancel appointments and set a rule to say that no appointments allowed to be cancelled 12 hours after appointment have been booked? Is it possible to have have two pages using the same settings of the easy appointments, e.t maybe use one page for bookings and the other page for rescheduling? Or can there be an alternative whereby instead I can use the confirmation tab for confirming emails and then the other for cancelling emails, but the cancelling of emails must allow cancellation within 12 hours of the booking time, after 12 hours the cancellation cannot be made. How do I do that using HTML?
