I've repleced the hardcode with the applicable associative array items, but still doesn't validate why?? echo "</ul>"

<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');

$contacts = array(array('name' => 'Alena Holligan'), array('name' => 'Dave McFarland'), array('name' => 'Treasure Porth'), array('name' => 'Andrew Chalkley'));

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