You can't save data to any Form. A Form does not store data; it's just
a tool, a window that allows you to view and edit data stored in a
Table. Data is stored in Tables, and only in Tables.
Normally you would use a Form bound to your table; navigate the form
to display the record that you want to edit, and just edit it there.
You can put a Combo Box on the form using the Wizard - choose the
option "Use this combo to find a record", and have it look up the Job
