Witam.
Proszę mi powiedzieć co mam nie tak w kodzie php lub html:

PHP

<?php

$mailto = 'martinszyd@poczta.fm' ;

$subject = "temat" ;

$formurl = "http://www.zqub.keep.pl/kontakt.html" ;
$errorurl = "http://www.zqub.keep.pl/error.html" ;
$thankyouurl = "http://www.zqub.keep.pl/index.html" ;

$uself = 0;

// -------------------- END OF CONFIGURABLE SECTION ---------------

$headersep = (!isset( $uself ) || ($uself == 0)) ? "\r\n" : "\n" ;
$name = $_POST['name'] ;
$email = $_POST['email'] ;
$comments = $_POST['comments'] ;
$http_referrer = getenv( "HTTP_REFERER" );

if (!isset($_POST['email'])) {
header( "Location: $formurl" );
exit ;
}
if (empty($name) || empty($email) || empty($comments)) {
header( "Location: $errorurl" );
exit ;
}
if ( ereg( "[\r\n]", $name ) || ereg( "[\r\n]", $email ) ) {
header( "Location: $errorurl" );
exit ;
}

if (get_magic_quotes_gpc()) {
$comments = stripslashes( $comments );
}

$messageproper =

"This message was sent from:\n" .
"$http_referrer\n" .
"------------------------------------------------------------\n" .
"Name of sender: $name\n" .
"Email of sender: $email\n" .
"------------------------- COMMENTS -------------------------\n\n" .
$comments .
"\n\n------------------------------------------------------------\n" ;

mail($mailto, $subject, $messageproper,
"From: \"$name\" <$email>" . $headersep . "Reply-To: \"$name\" <$email>" . $headersep . "X-Mailer: chfeedback.php 2.08" );
header( "Location: $thankyouurl" );
exit ;

?>
