The PartNumber control is a combo box and the Control source is my Part #
table and the Row source is also the Part # table.
Doublecheck that. The Control Source cannot be a table; it must be a field,
presumably NOT a field in the Part # table (there's no point in updating a
part number to itself!), but rather the part # field in your main form's
table.
The PartDescription
control is also a combo box and the Contorl source is the Part # table and
the Row source is my Part Description table. Is there is another way to
select a part number and for the description to also show up.
Typically the Parts table would have a PartNo (I'd avoid using the # character
in fieldnames) as a Primary Key, and a Description as a separate text field.
Your main table should NOT contain a description field; that should exist only
in the Parts table. However, it should have a PartNo field (I presume, I don't
know what table this form is updating).
This field could have two combo boxes bound to it. Both combos would use the
mainform table's PartNo as the Control Source; one would have a RowSource like
SELECT PartNo, Description FROM Parts ORDER BY PartNo;
and a ColumnWidths property of
0.5"; 1.5"
to display the PartNo when it's not dropped down and both fields when it is;
the second combo would have a RowSource
SELECT PartNo, Description FROM Parts ORDER BY Description;
with a ColumnWidths of
0"; 2"
to store the PartNo but display the description.
