G'day

I just can't seem to find the right answer to this one. Hopefully
someone can  point me in the right direction please. I have the
following function in a "app/controllers/models_controller.php".  I
load three select boxes two of which rely  on data from the first one.
I can enter a manual value into the array as you can see, and they
display the data fine,  but I can't seem to  figure out how to capture
the value of the current selected item from the first generateList to
feed it to the two others.

Can someone please enlighten me?.........;-)

 function index() {
        $this->set('models', $this->Modelinfo->Model-
>generateList(null, 'Model_Number', null,
'{n}.Model.Model_Number','{n}.Model.Model_Number', true, true ) );

        $this->set('modelinfos', $this->Modelinfo-
>generateList(array('Modelinfo.Model_Number'=> 'LD400'),null, null,
'{n}.Modelinfo.Model_Number','{n}.Modelinfo.AltModel_Number'));

        $this->set('altmodels', $this->Altmodel-
>generateList(array('Altmodel.Model_Number'=> 'LD400'),null, null,
'{n}.Altmodel.Model_Number','{n}.Altmodel.Alt_Model'));

        }

Thanks....
