PHP PHP Arrays and Control Structures PHP Arrays Multidimensional Arrays

Looking for error in my code...

Treehouse asks the following:

In the code below, we have a simple array of contact names. We want to use the $contacts array to fill in the hardcoded list of names an email addresses. To hold the email as well as the name for each contact, we need a multidimensional array, meaning each person in the contact list will have their own array. The first step is to make each person their own single item ASSOCIATIVE array, using 'name' as the key for these internal arrays.

I cannot find my error, I have searched a bunch. Any help is appreciated. Thanks.

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

Hi there! First, what you're doing is not necessarily wrong but it's not exactly what the challenge is asking for. They want you to set up a multidimensional array that will hold the name and email keys. But on this step, they only ask for you to set up the name key part of it. It won't be until step 2 of the challenge that you set up the email key, so you may want to copy/paste your code so you have a copy when you get to the next step.

Hope this helps, but let me know if you're still stuck! :sparkles:

The first question only wants the name. The second question, you will add the email addresses.
