I get a server error when doing this form heres all the code:

<?php

$first_name = $_POST['first_name'];

$last_name = $_POST['last_name'];

$email = $_POST['email'];

$username = $_POST['username']

$to = "TheorizedGaming@gmail.com";

$subject = "New Application!";

$message = "Hello, $first_name $last_name has just left us a form";

mail($to, $subject, $message, "From: " , $first_name . $last_name);

echo "Your message has been sent!";

 

?>

 

The error is at line 6($to)? Could someone help me?
