Hi Jeff,

Thanks for your reply. Your suggestion is a good one.
For the moment, though, I'm just trying to understand the
mechanism of how a combo box stores field data from one
table in the forms active table.

Are you saying you used a "lookup" data type in your
table? This may cause
you headaches later on, especially if your ZIPCode table
uses a primary key,
and your Contact table is storing the key, but
displaying the ZIPCode.

Rather than working directly in the table, consider
using a form to display
information. Build a combo box on the form that uses
the ZIPCode table as a
row source, and is bound to the Contact table ZIPCode
field. You would need
to change the "lookup" datatype to an appropriate
different type.
