//$contacts[0] will return 'Alena Holligan' in our simple array of names.

Hello all the steps are written.

First you need to edit the simple array given to you, to be an array of associative array with for each contact a key "name" for the name:

<?php

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

?>

The second step is to add a key "email" with the corresponding email:

<?php

$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')
);

?>

The third and last step is to replace the harcoded output, with the values of $contacts :

<?php

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";

?>
