Text not showing up on form

Hello everyone. i am a graphics guywith not much experience with web design, although i made this one all on my own.

i followed the tutorial from this site to apply a PHP contact form but for some reason the text is not showing up in the browser. http://www.jabridesign.com/Contact.htm

<form method=“POST” action=“mailer.php”>
<input type=“text” name=“name” size=“19”><br>
<br>
<input type=“text” name=“email” size=“19”><br>

<p>Please add any detailed information that may help with your inquiry.</p>
<textarea rows=“6” name=“message” cols=“30”></textarea>
<br>
<input type=“submit” value=“Submit” name=“submit”>
</form>

<?php

if(isset($_POST[‘submit’])) {

$to = "travis@jabridesign.com";

$subject = “Form Tutorial”;

$name_field = $_POST[‘name’];

$email_field = $_POST[‘email’];

$message = $_POST[‘message’];

$body = “From: $name_field
E-Mail: $email_field
Message:
$message”;

echo “Data has been submitted to $to!”;

mail($to, $subject, $body);

} else {

echo “blarg!”;

}

?>

i’ve uploaded both directories to my hostserver with no problems but i can’t seem to figure this out. any help?
