"It looks like Task 1 no longer passes." So I click "Go to task One" and check my work. It still passes. Is this a bug?

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

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