Hi Ayish, It seems this challenge requires to use multidimensional array in other words it's array in the array. I will give a little tip on the task. First you have a simple array like 

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

which you can access by 

echo $contacts[0];

The challenge wants you to use array in the array, so it would be something like that.

<?php
$contacts = array(
  array(
    'name' => 'Alena Holligan',
    'email' => 'alena.holligan@teamtreehouse.com'),
  array(
    'name' => 'Dave McFarland'...
);

echo "<ul>\n";
echo "<li>" . $contacts[0]['name'] . " : " . $contacts[0]['email'] . "</li>\n";
echo "<li>" . $contacts[1]['name'] ...

This is my first post, I hope it will help you to beat challenge:)
