Add a fourth parameter, $species, to the Trout constructor.

I'm really stuck. The error says that the constructor is not referencing the Trout class


class Fish
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record){
        $this->common_name = $name;
        $this->flavor = $flavor;
        $this->record_weight = $record;

    public function getInfo() {
        $output  = "The {$this->common_name} is an awesome fish. ";
        $output .= "It is very {$this->flavor} when eaten. ";
        $output .= "Currently the world record {$this->common_name} weighed {$this->record_weight}.";
        return $output;
class Trout extends Fish {

  public $species;

  public function __construct($name, $flavor, $record, $species) {
  parent::__construct($name, $flavor, $record);
  $this->$species = $flavor;

In your Trout constructor the line to set species should be

 $this->species = $species;

$species goes under the class Trout line
