Constuctor Method in OO PHP Basics

Hi,

I'm struggling with the Quiz section in the OO PHP Basics. I believe the problem is that the property names don't match the contructor variable names like in the demonstrated example. However I am just taking a stab in the dark as to how to fix it. I've tried swapping the "name" and "common_name" around but can't get it to accept my answer.

Please help :)

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;
    }

}

?>

Thanks a lot Corey :) I started afresh and came back to say I changed it to this and it worked:

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;
  }

}
