Trouble with printing out multidimensional arrays to html using echo in coding challenge

I created a multidimensional array correctly according to the code challenge. However, when printing it out below I use the array[#][STRING] format to print out the names and email addresses. When I finish, it gives me an error message. What is wrong with my code?

//edit this array
$contacts = 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";

your arrays are correct. just need to put curly braces.

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

Hi David! I think your issue is in the way you have your array set up. I did mine like this:

$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']);

The rest of my code looks like yours. I hope this helps!
