I guess you need to add this line
<input type=hidden name="redirect" value="yourdomain.com">

Not a pretty script, I'm afraid. The reliance upon Javascript is rather easy to avoid.

function clean_input_4email($value, $check_all_patterns = true)
{
 $patterns[0] = '/content-type:/';
 $patterns[1] = '/to:/';
 $patterns[2] = '/cc:/';

 if ($check_all_patterns)
 {
  $patterns[4] = '/\r/';
  $patterns[5] = '/\n/';
  $patterns[6] = '/%0a/';
  $patterns[7] = '/%0d/';
 }
 //NOTE: can use str_ireplace as this is case insensitive but only available on PHP version 5.0.
 return preg_replace($patterns, "", strtolower($value));
}

$name = clean_input_4email($_POST["name"]);
$email = clean_input_4email($_POST["email"]);
$thesubject = clean_input_4email($_POST["thesubject"]);
$themessage = clean_input_4email($_POST["themessage"], false);

$error_msg='ERROR - not sent. Try again.';

$success_sent_msg='<p align="center"><strong>&nbsp;</strong></p>
                   <p align="center"><strong>Your message has been successfully sent to us<br>
