i have a PHP contact form that submits data, and an email...:

<?php 
$dbh=mysql_connect ("localhost", "username", "password") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("guest"); 

if (isset($_POST['submit'])) { 

if (!$_POST['name'] | !$_POST['email']) 
{
echo"<div class='error'>Error<br />Please provide your Name and Email Address so we may properly contact you.</div>";
}
else
{
$age = $_POST['age']; 
$name = $_POST['name'];
$gender = $_POST['gender'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$comments = $_POST['comments'];

$query = "INSERT INTO contact_us (age,name,gender,email,phone,comments)
VALUES ('$age','$name','$gender','$email','$phone','$comments')";

mysql_query($query);

mysql_close();

$yoursite = "Mysite ";
$youremail = $email;

$subject = "Website Guest Contact Us Form";
$message = "$name would like you to contact them 
                            Contact PH:  $phone
Email:  $email
Age: $age
Gender: $gender
Comments:  $comments";

$email2 = "[email protected]";

mail($email2, $subject, $message, "From: $email");

echo"<div class='thankyou'>Thank you for contacting us,<br /> we will respond as soon as we can.</div>";

}
}
?>

The email is coming through fine, but the data is not storing the dbase... am i missing something? Its the same script as i use on another contact us page, only difference is instead of parsing the data on teh same page, i now send this data to a "thankyou.php" page... i tried changing $_POST to $_GET but that killed the page... what am i doing wrong?
