I am trying to select a record/s that a user can click and further record/s can be returned.
Say, a list of departments is displayed and a user clicks on Department1, which leads to Divisions 1 to 3 being displayed and Division2 is clicked and its Units are then displayed.
 
Department1------>Division1
                  ------->Division2------>Unit1
                                        ------>Unit2
                  ------->Division3
 
Rgds,
