code is right, but get error

I tested my code outside of this test, and it displays the flavors to the screen, but I still get an error saying I didn't use the same variable. What gives?

index.php 
<?php

$flavors = array();
$flavors[] = array("name" => "Cookie Dough",      "in_stock" => true);
$flavors[] = array("name" => "Vanilla",           "in_stock" => false);
$flavors[] = array("name" => "Avocado Chocolate", "in_stock" => false);
$flavors[] = array("name" => "Bacon Me Crazy",    "in_stock" => true);
$flavors[] = array("name" => "Strawberry",        "in_stock" => false);

//add your code below this line
foreach ($flavors as $key => $value) {
  echo $flavors[$key]["name"] . "<br />\n";
}
?>

It seems like you may have overthought the solution, take a look at this piece of code and see if it helps clarify what they were asking for.

foreach ($flavors as $flavor) {
  if($flavor["in_stock"] == true){
  echo $flavor['name'];
  }
}
