Barry-Jon's question is one that you should consider. If you still believe
that you need the second table, then read up on append queries in Help file.
You can use the form's AfterUpdate event to run a macro or VBA code that
will run a stored append query that will do what you seek. You can create
the append query and save it (for example, name it
"qry_Append_PeopleSettings"). This query can use a control on your form to
get the primary key value of the parent table, and then use that as the
value for the foreign key in the child table.
If you haven't already done so, I also recommend that you obtain a book on
ACCESS and become familiar with the basic information for queries, forms,
etc.
I am hesitant to post any more details, as I am not aware of your current
skill level and what I post may be unhelpful for you (either too basic or
too complex).
