How do I make this work?

My code works in preview but it doesn't get accepted. I am guessing it is because there is a much easier and shorter solution for this. What is it? I can't get it right.

index.php 
<?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 $contacts[0]['name'];
echo $contacts[0]['email'];



echo $contacts[1]['name'];
echo $contacts[1]['email'];

echo $contacts[2]['name'];
echo $contacts[2]['email'];

echo $contacts[3]['name'];
echo $contacts[3]['email'];

Replace the hard coded values in the output with the name and email values from the contacts array.

//This:
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
// Becomes:
echo "<li>". $contacts[0]['name']." : ".$contacts[0]['email']."</li>\n";

They wanted you to maintain the unordered list structure.

<?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";
