What am I missing in this code challenge?

I think I'm creating the getInfo() function correctly but it keeps saying it's wrong. Can someone show / explain what I'm missing here and why?

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;
     } 

  function getInfo(){
     return "A ". $this->$name . " is an ". $this->$flavor . "flavored fish.  The world record weight is " . $this->$record . ".";

  }

}
$bass = new Fish("Largemouth Bass", "Excellent", "22 pounds 5 ounces");
?>

trying the exact same code, the challenge passed for me. It seems your browser just needs a good refresh.

 <?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;
     } 

  function getInfo(){
     return "A ".$this->$name . " is an ".$this->$flavor . "flavored fish.  The world record weight is " .$this->$record . ".";

  }

}
$bass = new Fish("Largemouth Bass", "Excellent", "22 pounds 5 ounces");
?>

Hi Harry,

You are very close. You are just using the wrong variable names. $this is right, but you don't need the $ for the name, and you need to use the original variable names, not the ones pass in the argument.

function getInfo(){
  return "A ".$this->common_name . " is an ".$this->flavor . "flavored fish.  The world record weight is " .$this->record_weight . ".";
}

Hope that helps. Keep Coding! :)

Thanks guys. I redid it the way you explained it Jason and it worked. Yes, I just noticed that I don't need a $ in front of the name since $this->common_name is the variable.. already a $ there.

thanks. It's making a bit of sense now.
