Problem with concatenation returning 0's instead of entered text in Contact Form lesson of PHP.

Everything was working fine until I added Name:, Email: and Message: labels before variables. Now returning 0's. Any ideas whats wrong.

<?php
$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];

echo "Name: " + $name;
echo "Email: " + $email;
echo "Message: " + $message;
?>

The problem is you are using the wrong operator (symbol) to concatenate. In PHP you use a period to concatenate things together and not a plus sign. Your code should look like this:

<?php
$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];

echo "Name:  " . $name;
echo "Email:  " . $email;
echo "Message:  " . $message;
?>
