Assigning properties to parameters

Challenge Task 3 of 5 "In the new constructor method, assign each of the properties on the Fish class with its corresponding parameter variable."

I am told that "Be sure the $name parameter is assigned to the common_name property."

What am I missing from my code?

fish.php 
<?php

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

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

}

?>

If I am not mistaken you have the reference to the property name and the passed parameters backwards. Wouldn't it be in this example:

<?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; }

}

?>

(Changed ($this->name = $common_name;) to ($this->common_name = $name;) and ($this->record = $record_weight;) to ($this->record_weight = $record;)) The statement: "Be sure the $name parameter is assigned to the common_name property," is referring to $name as the parameter (or the variable in which the argument passed is stored) and common_name being the property (the variable which is part of class itself and the constructor is assigning to).

It works now, thanks!

<?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;
  }

}

?>
