In the code below, we have a simple array of contact names. We want to use the $contacts array to fill in the hardcoded 

<?php
//edit this array
$contacts = array('Alena Holligan' => 'alena.holligan@teamtreehouse.com'); 
$another = array('Dave McFarland' => 'dave.mcfarland@teamtreehouse.com'); 
$another1  = array('Treasure Porth' => 'treasure.porth@teamtreehouse.com'); 
$another2  =  array('Andrew Chalkley' => 'andrew.chalkley@teamtreehouse.com');

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

I don't really know what this challenge is asking for

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

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

$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";

here is what I ended up with I see maybe the space for the quote?

<?php
//edit this array
$contacts = array('Name' => 'Alena Holligan'); 
$another1 = array( 'Name' => 'Dave McFarland'); 
$another2  = array('Name' => 'Treasure Porth'); 
$another3  =  array('Name' => 'Andrew Chalkley');

Still does not work. What am I missing

This code worked ok for me:

$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",
    )
    );

I'm having the same issue. The first step is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays. The above should be correct

$contacts = array( 
  $contact1 = array( "name" => "Alena Holligan", ), 
  $contact2 = array ( "name" => "Dave McFarland",), 
  $contact3 = array( "name" => "Treasure Porth", ), 
  $contact4 = array( "name" => "Andrew Chalkley",) 
);

this worked for 1 of 3 I rechecked your example and it worked as well for 1 of 3 after removing the email

@Philip Legault Indeed, it looks like you cannot anticipate in this challenge;)

For task 3, I have the following code (nothing wrong with it in theory) but it's not passing:

echo "<ul>\n"; 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";

Please advise.
