Having trouble with 3rd part of multidimensional array exercise

Seemed to have followed the syntax rules and exercise rules, but it tells me that I shouldn't be modifying output at this point. Confused.

index.php 
<?php
//edit this array
  $contacts[] = array(
    'name' => 'Alena Holligan',
    'email' => 'alena.holligan@teamtreehouse.com',
  );

  $contacts[] = array(
    'name' => 'Dave McFarland',
    'email' => 'dave.mcfarland@teamtreehouse.com',
  );

  $contacts[] = array(
    'name' => 'Treasure Porth',
    'email' => 'treasure.porth@teamtreehouse.com',
  );

  $contacts[] = 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";

Andren, thank you! Just adding those curly brackets solved my issue.

The issue is that you can't embed multidimensional arrays within a string using normal variable interpolation in PHP. This is due to the fact that PHP cannot figure out where the variable ends and regular text begins.

To embed the array within the string you have to place curly braces around the variable you want to embed, like this:

<?php
//edit this array
  $contacts[] = array(
    'name' => 'Alena Holligan',
    'email' => 'alena.holligan@teamtreehouse.com',
  );

  $contacts[] = array(
    'name' => 'Dave McFarland',
    'email' => 'dave.mcfarland@teamtreehouse.com',
  );

  $contacts[] = array(
    'name' => 'Treasure Porth',
    'email' => 'treasure.porth@teamtreehouse.com',
  );

  $contacts[] = 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";

This is an example of what is called the Complex Syntax for string interpolation in PHP. With that change your code will pass the challenge.
