Hi!
I must take the value (or values) choose in a checkbox and print in my page. What I wrote is wrong, can you help me to correct?

new CheckboxSetField(
            $name = "categoria",
            $title = "Categoria:",
            $source = array(
             "1" => "5L stelle",
             "2" => "5 stelle",
             "3" => "4 stelle",
            "4" => "3 stelle"
             )

function doRicettivita($data, $form) {
      if(!empty($data['nome'])) //this is a textfield
      { $data = array('Nome' => $data['nome'], 'Categoria' => $data['categoria']);
      }
      //return $a;
      return $this->customise($data)->renderWith(array('SearchPage_results', 'Page'));
