registration form

[mwq27]

Whenever I hit submit from the HTML form, I get a blank screen on the php page.  There is something wrong with my code and I just cant figure it out. 
Here is the code [code]<?php

echo 'HWHEEADONASOIOAIDHOIAD';

$host = 'localhost';
$user = 'root';
$pass = 'xxxxx';
$dbname = 'pecs';

$link = mysql_connect($host, $user, $pass);

if(!$link)
{
die("Could not connect: " .mysql_error());
}
mysql_select_db($dbname, $link) or die (" Database not found." . mysql_error());


$email = $_POST['email'];


$name = $_POST['name'];

$title = $_POST['title'];

$address = $_POST['address'];

$city = $_POST['city'];

$state = $_POST['state'];

$zip = $_POST['zip'];

$phone = $_POST['phone'];

$org = $_POST['org'];

$regreg = $_POST['regreg'];

$stureg = $_POST['stureg'];


if(empty($email) || empty($name) || empty($address) || empty($city) || empty($state) || empty($zip) || empty($phone) || empty($org))
    {
    echo 'you didnt fill in all the required fields! go back and do it again...';
  //  echo "<a href=\"javascript:history.go(-1);\">&laquo; back</a>";
    } else {

          // Check to make sure its a valid email, and already exists

        if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {

            $check_email = "SELECT * FROM regform WHERE email='$email'";

                $result = mysql_query($check_email) or die (mysql_error());


                    if (mysql_num_rows($result) > 0) {

                        $email = FALSE;

                        echo 'That email is already being used!<br />';

                    }
//if a radio button hasnt been selected
if(!isset($regreg) && !isset($stureg))
{
echo 'Please select whether you student registration or regular registration.'; }
else {

//set variable to the right radio button
if(!isset($regreg))
{
$regreg = $_POST['stureg'];
}
else $regreg = $_POST['regreg'];

$sql = mysql_query("insert into regform (name, org, title, address, city, state, zip, phone, email, regbef) values ('$name', '$org', '$title', '$address', '$city', '$state', '$zip', '$phone', '$email', '$regreg')");
$result = mysql_query($sql);

if(!result)
echo 'could not register you try again';
//throw new Exception('Could not register you, try again');
else
echo 'Success!!';

}


?>
[/code]

Could someone please tell me what is wrong here.  Thanks
