First of all I must thank you for your reply...it had worked but another problem has come up...there is this error which comes up in a pop-up form...

Run-time error '2115'

The macro or function set to the BeforeUpdate or ValidationRule property for this field is preventing P. B. Reservation System from saving the data in the field.

I don't understand this problem.

I have a couple of other problems.
- adding a date field with integer and outputting it in another field.
DepartureDate = ArrivalDate + NumberOfNights

Departure date must be calculated autonatically after you enetr ArrivalDate and NumberOfNights.

- saving the date on which the reservation was made by the user of the application...not the day the client want to reserve a room.
