how to add property name 'species'?

not sure how to add $species to the Trout class. Thanks!

fish.php 
<?php

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 $output;
    }
}   class Trout extends Fish {
        function __construct($name, $flavor, $record) {
             parent::__construct();
                 $this->common_name = $name;
                 $this->flavor = $flavor;
                 $this->record_weight = $record;
    }            
        $species;

}

?>

this is what I did. Doesn't see working.

        class Trout extends Fish {
        function __construct($name, $flavor, $record, $species){
        parent::__construct();
        $this->common_name = $name;
        $this->flavor = $flavor;
        $this->record_weight = $record;
        $this->species = $species;
      }
    }

Hey Logan,

You would make the change in your fish class construct not in the Trout class.

Hope that helps
