To add a room or equipment to an appointment make sure the room/equipment has been set up. 

Make an appointment in the usual way.

Select Assign a room/equipment on the left hand side.

Select the room/equipment you wish to assign to the appointment from the drop down list.

The booked room/equipment colour will show on the Appointment. 

When the room/equipment is booked it will show as unavailable in the list.

 Note: It is possible to double book the room/equipment. However this will show as a diagonal striped line in the appointment to indicate it is already booked.
