For some strange unbeknown reason my contact form has just stopped working in that it no longer submits any of the form details to the email address I have set up in the script.

The contact form does re-direct to the thanks.htm file once the approapriate field data has been completed and then submitted, its just it ends at that point..!

I tested the PHP / contact form on several occasions whilst live and on every occasion I had the form details come through to my email account, so Im at a loss as to why it has just stopped ?

My code for the PHP and HTML is as follows should anyone anyone be kind enough to look at it : (Domain is also

PHP Code:
/* Set e-mail recipient */
$myemail  "";

$company  = ($_POST['company']);
$firstname = ($_POST['firstname']);
$email    =($_POST['email']);
$enquiry =($_POST['enquiry']);
$thanksurl "" ;
$errorurl "" ;

/*Redirects the user to the error page if JS is disabled and the form is submitted*/
header('Location: error.html');
/* Redirects the visitor to the thanks page */
header('Location: thanks.htm');

/* Prepare the message for the e-mail */
$message "You have a new Web design enquiry from:

Company name: 
Client name: 
Clients e-mail: 
Clients message: 
End of message

/* Sends the message using mail() function */

HTML Code:
<form action="contact.php" method="post" name="contactForm" onsubmit="return validateForm()">
					<p><span>*</span> Must be completed to submit the form</p>
							<input type="text" name="company"/>
