<?
if($word_ok!==false)
{
    if($word_ok=="yes")
    {

$to=$_POST['to'];
$subject=$_POST['subject'];
$body=$_POST['body'];
$from=$_POST['from'];
$headers = "From: $from" . "\r\n" .
    'MIME-Version: 1.0' . "\r\n" .
    'Content-type: text/html; charset=iso-8859-1' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

//mail($to,$subject,$body,$headers);

    if (@mail ($to, $subject, $body, $headers)) {

echo "Email successfully sent to $to.";
echo "<Br>Click <a href='mail.php'>here</a> to send another.<br />";
    } else {
echo "Error sending email!";
}
    } else {
        echo "The word you entered for the image verification did not match what was displayed.<br />"; 
    }
}
?>

Thats part of my email script, when I click the submit button none of that echos on the page, is there anything wrong with this script?

If you want rest of the script then I'm using freeCap PHP CAPTCHA Version 1.4.1
