Hi, I have a contact page with a contact form that posts to my contact.php but when I test and submit it via the website I get this "Error!"

below is my form

 <form action="contact.php" method="post" id="contactform">
          <ol>
            <li>
              <label for="name">First Name <span class="red">*</span></label>
              <input id="name" name="name" class="text" />
            </li>
            <li>
              <label for="email">Your email <span class="red">*</span></label>
              <input id="email" name="email" class="text" />
            </li>

        <li>
          <label for="company">Contact No.</label>
          <input id="company" name="company" class="text" />
        </li>
        <li>
          <label for="subject">Subject</label>
          <input id="subject" name="subject" class="text" />
        </li>

          <label for="message">Message <span class="red">*</span></label>
          <textarea id="message" name="message" rows="6" cols="50"></textarea>
        </li>

        </li>
      </ol>
    </form>

below is the contact.php

<?php

if(!$_POST) exit;

$email = $_POST['email'];

if (!preg_match('/[a-z0-9!#$%&\'*+\/=?\^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+\/=?\^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/', $email)) {
  $error.="Invalid email address entered";
  $errors=1;
} else {
  // email is ok!
} 

if (!empty($errors)) 
{ 
  if ($errors==1) echo $error;
} 
else{
	$values = array ('name','email','message');
	$required = array('name','email','message');

$your_email = "[e-mail]";
$email_subject = "New Message: ".$_POST['subject'];
$email_content = "new message:\n";

foreach($values as $key => $value){
  if(in_array($value,$required)){
	if ($key != 'subject' && $key != 'company') {
	  if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
	}
	$email_content .= $value.': '.$_POST[$value]."\n";
  }
}

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