I want to create a table with drop down (look Up?) field that restricts the
next drop down box in the next field. I want to select a model in one
field.
Based on that selection, a list of options pertinent only to that model
are
the only ones to filter(?) in the drop down box in the next field.

What is this called? I have 3 access books and cannot find it.
