I am having 2 face-to-face activitieswith some sessions. When we have sessions of same date and time inside different activities as shown below, it is allowing to book. I need to restrict the booking for a session if already booked for particular date and time even though session is in different activity.
|You are booked for the following session:||Options:|
|23 December 2011||10:00 AM - 12:00 PM||
Could you please help me how to provide this feature of not booking for a session on same date and time inside another face-to-face activity.
