- Use a TableLookup to get the information out of the second table. Edit the
- detail table using the imbedded form, then specify the table lookup under Val
- checking. In fact, if you use HelpAndFill, the person entering the data
- can choose the desired serial number off a table-view list.
- The only disadvantage of this method is that the serial numbers to be
- entered must _already_ exist in the lookup table, because only s/n-s from
- that table will be valid entries.
