Problem adding Captcha to script

[fullyloaded]

hi

i was wondering if anyone can give me a hand adding this captcha script? i have tried everything i can think of with no luck at all. I think my problem has to do with the session where i already have one started  but i could be wrong, any help would be great thanks.

 

My code:

<?php
include("db.php");
$error_message="";
$email_to    = mysql_real_escape_string(strip_tags($_POST['email_to']));
$today = date("M d, Y h:i A");
$ip = $_SERVER['REMOTE_ADDR'];
if (isset($_POST['submit'])){
    if($_SERVER['REQUEST_METHOD'] == 'POST')
    {
        if(!isset($_SESSION['csrf']) || $_SESSION['csrf'] !== $_POST['csrf'])
        $sql = "SELECT username FROM users
        WHERE mailaddress = '{$email_to}'";
        $result=mysql_query($sql, $conn)
        or die('Error in query:<br>'. $sql .'<br>'.mysql_error($conn).'<br>Time of Error: '.date("l F j, Y, G:i:s T"));
        $count=mysql_num_rows($result);
        if($count==1){
            $rows=mysql_fetch_array($result);
            $username=htmlentities($rows['username']);
            $to=$email_to;
            $subject="mysite Username reminder.";
            $header="from: noreply@mysite.com";
            $messages= "Hey $username, \r\n";
            $messages.=" \r\n";
            $messages.="You recently request your mysite username on $today \r\n";
            $messages.=" \r\n";
            $messages.="Your username is: $username \r\n";
            $messages.=" \r\n";
            $messages.="You can sign in at: https://www.mysite.com \r\n";
            $messages.=" \r\n";
            $messages.="Your username was requested from the following ip address: $ip \r\n";
            $messages.=" \r\n";
            $messages.="Thanks, \r\n";
            $messages.="From mysite.com \r\n";
            $sentmail = mail($to,$subject,$messages,$header);
        }
        else {
            $error_message = 'Sorry email address not found.';
        }
        if($sentmail){
            $error_message = 'Your username has been sent to your email address.';
        }
        else {
            $error_message = 'username was not sent please try again.';
        }
    }
}
$key = sha1(microtime());
$_SESSION['csrf'] = $key;
?>

 

Captcha code trying to add:

<?php
session_start();
if (md5($_POST['csrf']) == $_SESSION['csrf']){
    $error_message = 'Captcha good.';
    } else {
    $error_message = 'Captcha wrong.';
}
?>
