    }

";
  }

if(@mail($your_email,$email_subject,$email_content)) {
    echo 'Message sent!'; 
} else {
    echo 'ERROR!';
} 
     }
     ?>

Your code is very messy.

no offense, but you need to work on making proper indents so you can clearly see the problem.

Here is a cleaner version of your code.

$required = array('name','email','message');
$temp = '';
$err = array();
foreach ($required as $value) {
    if ($_POST[$value] == '') $err[] = 'Field '.$value.' is required';
    $temp .= $value.': '.$_POST[$value]."
";
}

if (count($err) > 0) {
    echo implode('<br />',$err);
    exit;
}

$your_email = "xxxxxxxxx@gmail.com";
$email_subject = "New Message: ".$_POST['subject'];
$email_content = "new message:
".$temp;

if (mail($your_email,$email_subject,$email_content)) echo 'Message sent';
else echo 'Message not sent';
