In generaly, the replacement part table should contain only a single foriegn
key that references the primary key of the parts table. You would have 2
combo boxes in the subform, each with a hidden bound column for the primary
key, one that has the part number in the first visible column, and one that
has the description in that column. Both if these combo boxes should be bound
to that same foreign key field, so when you make a selection in one, the other
automatically reflects that change.
Note that the primary key should usually be a hidden Autonumber key (a
surrogate key), not the human-readable part number. You should have the part
number be a "logical key" by making it indexed: Yes (No duplicates), but it's
better to have the -primary- key be "just a number", so you can change a "part
number" logical key if you need to with no consequences for the relationships.
