notice driving me crazy

hello buddies,

this

Code:

<?php
class Portal extends Controller {

  public $data;
  function Portal()
   {
    parent::Controller();
    $data['poll'] = $this->MEncuestas->displayPoll(); // load question.
    extract($data['poll']); // extract id from poll.
          
    $data['options'] = $this->MEncuestas->displayOptions($id); //(I get undefined index id )

while in the localhost it doesn't show any notice msg, but when i upload the files to the server I get the undefined index id message.. so how can i correctly extract the $id from the $data['encuesta'] array and use it in the second query?

thanks in advance
