I am trying to create a form that will display address information in two different sub-forms from the same tables on the same screen at the same time. There are three tables (Customers, Addresses and Contracts). In the Customer Table the primary field is "CustomerId" which is text (field size 10) and has a one to many relationship with CustomerId fields in both the Addresses and Contracts tables. Contracts sometimes involve more than one customer (i.e. the contracting a/k/a the paying customer and the location customer) so a "LocClientId" field was added to all three tables in addition to the "CustomerId" field (text field size 10). But I can't get anything related to the LocClientId to work on my subforms. Your help would be much appreciated.
 
Why does each Customer have multiple addresses? Is one shipping, one billing, etc, or are there multiple entities within a Customer, each with their own address? What is "Loc"?
