Hello, I'm having a problem with Windows Access AutoID number being returned when I'm expecting my OrderID number that I need to link records in another table.  I Have two tables, a CustomerList, and CustomerParts.  I set up a Customer number FIELD in the CustomerList table that works well and increments properly to reference customer records.  Now I need that number in the CustomerParts table to log all parts bought for that customer with the customer in the CustomerList table.  I use a Combo box to see the Customers in the CustomerList table when entering parts in the CustomerParts table.  When I click on a customer record in the Combo Box list and see that it is really 10 for example, what is returned into my Parts CustomerNumber Number Field in the CustomerParts table is the Access AutoID number for CustomerID record number 10. That Customer number 10 that I generated for that customer is what I really want, not the AccessID number that represents it.   Why is that and can I fix it.   Thank you for your help in advance.  Horace Conti
