Great Day, I am trying to create an estimate for a customer that is having repair work done to his/her vehicle. When I click the customer's vehicle which the estimate is for, Access is requesting a parameter value for CustomerID. I know this sounds like a broken record from programmers of my skill level, but I've looked at every query and field name on the forms, but have been unable to discover why there is a CustomerID that does not have a value.
I have enclosed a copy of the db with the following instructions:
Click on frmCustomerContactData
highlight vehicle to be serviced
click "Repair Order" button
Thanks in advance for your assistance.
