I have attached a database that contains three Tables and three Data Entry Forms for the tables. The Tables Are; Point of Interest, Vehicles, and Weapons. I need the capability to verify if a Driver License Number exists in the Point of Inrterest Table if the Driver License Number is entered in the Vehicle or Weapon Table. I want an error message to appear when a user tries to enter a Driver License Number on the Vehicle or weapon table in the Driver License TextBox field. If the Driver License Number exists allow the saveing of the record. If the Driver License Number does not exist I want a mesage that one has entered a Driver License Number that does not exist. How can this be done with VBA in ACcess and what property area should the coding be put on a form. Should the arae be on an after update event or on a On-Click event?
I have attached a sample database I created from scratch real quickly. CFould you maybe show me some coding how this can be done in VBA?
