Challenge says $flavor is not being echoed. I'm pretty sure my answer is correct. Could this be a bug?

Not sure why $flavor is not echoing to page. I've even tried placing my echo statement below the return.

output.php 
<?php
include_once('flavor.php');
echo "Randy's favorite flavor of ice cream is ".$flavor.".";
$flavor = get_flavor();
return $flavor;

?>

The big problem here is that you're trying to echo something you haven't gotten yet. You have to define the flavor variable then call the method that's in the flavor.php file and set the value of flavor to the value returned by that method. The minor thing is that you don't need a return statement at all. Your code isn't wrong per sé... it's just a bit misordered. Take a look at my solution:

<?php
include_once('flavor.php');
$flavor = get_flavor();
echo "Randy's favorite flavor of ice cream is ".$flavor.".";

?>

Moral of the story: in most languages you can't use a variable you haven't defined yet. Happy coding!
