Arrival Date - Departure Date?
How would I go about writing a auto-calculation or validation rule, where a field named "Number of Nights" is automatically inputted based on the "Arrival Date" field - the "Departure Date" field?
How would it take into account where the booking rolls into another month... for example 30/01/2015 to the 07/02/2015? I want it to be able to input the number of days the booking is for automatically.
Thanks in advance,
