Adding Dates

[Ange Kappas]

I have a field with arrival date then a field with days and another field
with departure date. I enter a date in the arrival date field, then I put in
how many days as a number in the days field and using a Macro command on
exit I want the departure date to show automatically the arrival date plus
the days.
How do I do it ?

You don't.
Access is a database, not a spreadsheet.
All you need do is store (in your table) the [ArrivalDate] and the
[Days].
Then whenever you need the Departure date, simply calculate it.
In a query:
DepartureateAdd("d",[Days],[ArrivalDate])

Directly on a form or in a report, using an unbound text control:
=DateAdd("d",[Days],[ArrivalDate])

Set the Control Source of the departure date command to

=DateAdd("d", [NumberOfDays], [ArrivalDate])

You should almost surely NOT store all three values in your table, since the
departure date can be calculated from the other two. If you store all three
then you'll be at risk of data anomalies such as ArrivalDate = 1/27/2008,
NumberOfDays = 100, and DepartureDate = 2/1/2008. One of these must be wrong
but there's no immediate way to tell which!
