Printing an array in an unordered list is giving the requested result but the program says its wrong

The problem requires me to replace the hardcoded strings with the elements of an array in an unordered list. I did this and the results print out in the required format, but the program says the output is incorrect.

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

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>", $contacts[0]['name'] . " : " . $contacts[0]['email'],"</li>";
echo "<li>", $contacts[1]['name'] . " : " . $contacts[1]['email'],"</li>";
echo "<li>", $contacts[2]['name'] . " : " . $contacts[2]['email'],"</li>";
echo "<li>", $contacts[3]['name'] . " : " . $contacts[3]['email'],"</li>";
echo "</ul>\n";

//edit this array

Ok, the problem is of syntax: Look your this line in your code:

<?php
echo "<li>", $contacts[0]['name'] . " : " . $contacts[0]['email'],"</li>";

something is weird, right? You have to change the ',' for '.' after the "<li>" and before "</li>", and this is it, like this:

<?php
echo "<li>". $contacts[0]['name'] . " : " . $contacts[0]['email']."</li>";
echo "<li>". $contacts[1]['name'] . " : " . $contacts[1]['email']."</li>";
echo "<li>". $contacts[2]['name'] . " : " . $contacts[2]['email']."</li>";
echo "<li>". $contacts[3]['name'] . " : " . $contacts[3]['email']."</li>";
.
