You need to concatenate your values inside your getInfo() method with a ".", like so:

<?php

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

Hope that helps!!

Hi thanks grace, i figured the problem was that i put the extra "$" signs in the return statement. and concatenation is only needed with single quotes with the double quotes it works now :D.
