The template variables will only work if you have entered text in SETTINGS->PROPERTIES->ROOMS->SET UP "Unit Names". The context help for this setting will explain how to do this.
'''Example 11''' - Automatically set a flag for a bookings from a a channel which have breakfast included :
Trigger tab:
*Trigger Event = After Booking
*Time Offset = Immediate
*Booking Source = Booking.com (for example)
*Booking Field Contains - select "API Message" in the next field enter: meal_plan=Breakfast (use the text the channel uses)
Booking tab:
*Execution = One time only
*Flag Text = The text you want to display
*Flag Colour - choose the flag colour
Booking changes are applied before the mail is sent so that the flag template variable can be reflected in the email.
