When using a combo box to select a customer's name, I would like the address for that customer to be placed on the form automatically. How can this be done?

Various ways to do that.
For example, you base your combobox on a query that gathers not only the Customer s name but also his adress.
you make the adres colomn of the combo invisible (ex: column width 5cm;0cm where 5cm is for the customers' names column and 0 for the adressers column).
From the after update event of the combo, you uptdate the value of n unbound textbox on your form:

Me.AdressTextBox = Me.CustomersCombo.Column(1)

(combo columns are numbered from 0 : 1st column)
