I have a table that uses an identifying number for each customer. I also have an identifying number for a geographical area (1-8) When I create reports etc, I need the geographical number to be automatically populated with the customer ID. Note: (I don't see how this makes a difference, but the customer ID is a 4 or 5 digit number. It is unique, but not sequential). I am new to access and have multiple tables created and/or to create. Iuse these tables in a HIPAA/FISMA secure environment and so each table must be limited to 3 or 4 fields. Thank you.
