Stuck on OOP Basics Challenge!

Hi, I can't figure out what I am missing! Challenge Task 3 of 7 asks me to:

Add a property named species to the Trout class.

Bummer! Did you add the species property to the Trout class?

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

}

?>

What am I doing wrong? Can someone please help?

Remember that a property, inside of a class is basically a variable, that would be set with a $ symbol.

It it's asking you to set is outside of both the parent and child construct functions, but inside of the class.

Thanks a lot for the tip! I hate these silly mistakes! :D

For the future reference, the answer is: 

<?php
class Trout extends Fish
{
  public $species;

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

}
?>

Glad you got it! No problem! It is a lot to take in, I struggle with remembering what's what myself still.

Yep, I agree. I guess I have to do a lot of reading to have a better understanding. Thanks again! :)
