PHP Email Form Not Working

Below are the HTML and PHP files that I made for my email form. The form is not emailing me any response and I can not figure out why. Please help.

<?PHP
$to = "fastschedule@moureys.com";
$subject = “Fast Schedule Form”;
$headers = “From: My Site”;
$forward = 1;
$location = “http://www.moureys.com”;

$date = date (“l, F jS, Y”);
$time = date (“h:i A”);

$msg = "Below is the result of your feedback form. It was submitted on $date at $time.

";

if ($_SERVER[‘REQUEST_METHOD’] == “POST”) {
foreach ($_POST as $key => $value) {
$msg .= ucfirst ($key) ." : ". $value . "
“;
}
}
else {
foreach ($_GET as $key => $value) {
$msg .= ucfirst ($key) .” : ". $value . "
";
}
}

mail($to, $subject, $msg, $headers);
if ($forward == 1) {
header (“Location:$location”);
}
else {
echo “Thank you for submitting our form. We will get back to you as soon as possible.”;
}

?>

and the HTML Form goes like this…

<form action=“mailer.php” method=“post”>
<label>
<input name=“name” type=“text” class=“FastSchedule” id=“name” size=“28” />
<input name=“address” type=“text” class=“FastSchedule” id=“address” size=“28” />
