i can't get the Challange Task 3 of 3 ritght. i tried it out on the workspace, it worked perfectly, but not here.

<?php
//edit this array
$contacts[] = array(
  'name' => 'Alena Holligan', 
  'email' => 'alena.holligan@teamtreehouse.com',
  );
 $contacts[] = array(
   'name' => 'Dave McFarland', 
   'email' => 'dave.mcfarland@teamtreehouse.com',
   );
$contacts[] = array(
  'name' => 'Treasure Porth', 
  'email' => 'treasure.porth@teamtreehouse.com',
  );
  $contacts[] = array(
    'name' => 'Andrew Chalkley',
    'email' => 'andrew.chalkley@teamtreehouse.com',
  );


//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo " " . $contacts[0]['name'] . " : "  . $contacts[0]['email'] . "\n";
echo " " . $contacts[1]['name'] . " : "  . $contacts[1]['email'] . "\n";
echo " " . $contacts[2]['name'] . " : "  . $contacts[2]['email'] . "\n";
echo " " . $contacts[3]['name'] . " : "  . $contacts[3]['email'] . "\n";
