Lorraine, I don't quite understand what you're trying to do. Are you saying that the customer record already has the different phone numbers and you want the user to pick a phone number type (business, fax, etc.) from a combo box and have that number displayed? Yes, a DLOOKUP in an AfterUpdate event for the combo box should do that. I'm curious as to why you're setting the database up this way (instead of just showing all of the numbers in a subform).
