How to get correct value in a multi-dimensional array with associative arrays?

I set the code according to the proposed formatting however I am getting an error. Can someone help me see what I am missing here?

index.php 
<?php
//edit this array
$contacts = array(

    ['name'=>'Alena Holligan', 'email'=>'alena.holligan@teamtreehouse.com'], 
    ['name'=>'Dave McFarland', 'email'=>'dave.mcfarland@teamtreehouse.com'], 
    ['name'=>'Treasure Porth', 'email'=>'treasure.porth@teamtreehouse.com'], 
    ['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> $contact[0]['name'] : $contact[0]['email']</li>\n";
echo "<li> $contact[1]['name'] : $contact[1]['email']</li>\n";
echo "<li> $contact[2]['name'] : $contact[2]['email']</li>\n";
echo "<li> $contact[3]['name'] : $contact[3]['email']</li>\n";
echo "</ul>\n";

Did you check the preview?

Yes, I checked preview. However I am set up mostly in a mamp environment writing code in sublime and viewing through a web browser to see results. The code is not working as I was expecting. I am unsure how to correct the syntax to call for the correct value. I thought that all I needed to do was reference the key from the associative array after referencing the key from the top layer of the first array. What am I missing?

Simple error was that I had var named wrong but fixing that only created a new error. I am still not getting values to show. New error is about "Array to string conversion in index.php". I still don't really get how to output these values.

Try concatenation. Like this:

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

Thanks, that looks like it will do the job. I just wasn't connecting the syntax.
