My code won't pass. I have no idea why this won't pass when it has the correct output.

<?php //edit this array

$alena = array( 'name' => "Alena Holligan", 'email' => 'alena.holligan@teamtreehouse.com' ); $dave = array( 'name' => "Dave McFarland", 'email' => 'dave.mcfarland@teamtreehouse.com' ); $treasure= array( 'name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com' ); $andrew = array( 'name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com' );

$contacts = array( $alena , $dave , $treasure , $andrew );

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

index.php 
<?php
//edit this array

$alena = array( 'name' => "Alena Holligan", 'email' => 'alena.holligan@teamtreehouse.com' );
$dave = array( 'name' => "Dave McFarland", 'email' => 'dave.mcfarland@teamtreehouse.com' );
$treasure= array( 'name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com' );
$andrew = array( 'name' => 'Andrew Chalkley', 'email' => 'andrew.chalkley@teamtreehouse.com' );

$contacts = array( $alena , $dave , $treasure , $andrew );

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

echo "</ul>\n";

Checking your code had me scratching my head for a bit too. The original output included a newline (\n) after each closing </li> tag and that's needs to be added back in for each item. I'm not really sure why it's even there; it seems redundant given that a list item, by default, goes on a new line.
