Am I missing something?

I am trying to get a submit form working but I think I might be missing something - either that or it might not be working because the website isn't live.

This is the form part of the webpage.

<div class="contact">
                            <div id="contact_form">
                                <form name="form1" id="ff" method="post" action="contact.php">
                                    <label>
                                    <span>Enter your name:</span>
                                    <input type="text"  name="name" id="name" required>
                                    </label>
                                    <label>
                                    <span>Enter your phone number:</span>
                                    <input type="text"  name="phone" id="phone" required>
                                    </label>
                                    <label>
                                    <span>Enter your email:</span>
                                    <input type="email"  name="email" id="email" required>
                                    </label>
                                    <label>
                                    <span>Your message here:</span>
                                    <textarea name="message" id="message"></textarea>
                                    </label>
                                    <center><input class="sendButton" type="submit" name="Submit" value="Submit"></center>
                                </form>
                            </div>
                        </div>

And here is the php I am using.

<?php

$text = "<span style='color:red;'>Error! Please try again.</span>";

if(isset($_POST['name']))
{
$name=$_POST['name'];
$phone=$_POST['phone']
$email=$_POST['email'];
$message=$_POST['message'];

$to = "enquiries@website.com";
$subject = "Web Enquiry Submission";
$message = " Name: " . $name ."\r\n Phone: " . $phone ."\r\n Email: " . $email . "\r\n Message:\r\n" . $message;

$from = "**Not_Sure_What_Goes_Here**";
$headers = "From:" . $from . "\r\n";
$headers .= "Content-type: text/plain; charset=UTF-8" . "\r\n"; 

if(@mail($to,$subject,$message,$headers))
{
  $text = "<span style='color:blue;'>Your Message was sent successfully !</span>";
}
}
?>

Any help would be appreciated.

Cheers.
