Hi Modure,

The issue here is actually your choice of concatenation character. Instead of +, PHP uses a . to concatenate strings together so you'll want to do something like this.

<?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";
