Hi im kinda new in cakephp and having a lot of trouble adjusting.. Here's my biggest problem ..

Im trying to pass a parameter to an action, it does load, but when my script goes from the controller to the view, and goes back to the controller again, its gone.

CONTROLLER CODE

 function add($mac = 0)
{


if(isset($this->params['form']['medico'])) 
{

 $temp= $this->Person->find('first', array('conditions' => array('smartphones_MAC' => $mac)));
 $id= $temp['Person']['id'];

$this->Union->set('events_id', $id+1);
$this->Union->set('people_id', $id);
$this->Union->save();

}

VIEW CODE (This is a menu, i only have one button right now)

 <fieldset>

 <legend>SELECCIONE SU ALERTA</legend>

 <?php 

  echo $form->create('Event'); 

  echo $form->submit('EMERGENCIA MEDICA',array('name'=>'medico')); 

  echo $form->end();

  ?> 

  </fieldset>
