PHP login script won't redirect

Hi, I have a login php script that wont work, more specifically, redirect to the home page after accepting the the username and password. The page just goes blank afterward. I have been trying to work with this script for like a month and still can't get it to work right. Please, please help!

This is my registration php script:

<html>
<head>

<title>untitled</title>

</head>
<body><center><object type="application/x-shockwave-flash" allowScriptAccess="never" allowNetworking="internal" height="120" width="585" data="http://example.com/logo.swf">
<param name="allowScriptAccess" value="never" />
<param name="allowNetworking" value="internal" />
<param name="movie" value="http://example.com/logo.swf" />
<param name="play" value="true" />
<param name="loop" value="false" />
<param name="quality" value="high" />
</object>
<body bgcolor="black"><body text="red">

<?php
// Connects to your Database
mysql_connect("mysql", "username", "password") or die(mysql_error());
mysql_select_db("Users") or die(mysql_error());

//This code runs if the form has been submitted
if (isset($_POST['submit'])) {

//This makes sure they did not leave any fields blank
if (!$_POST['username'] Ś !$_POST['pass'] Ś !$_POST['pass2'] ) {
die('You did not complete all of the required fields');
}

// checks if the username is in use
if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);
}
$usercheck = $_POST['username'];
$check = mysql_query("SELECT username FROM Users WHERE username = '$usercheck'")
or die(mysql_error());
$check2 = mysql_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}

// this makes sure both passwords entered match
if ($_POST['pass'] != $_POST['pass2']) {
die('Your passwords did not match. ');
}

// now we insert it into the database
$insert = "INSERT INTO Users (username, password)
VALUES ('".$_POST['username']."', '".$_POST['pass']."')";
$add_member = mysql_query($insert);
?>

<h1>Registered</h1>
<p>Thank you, you have registered - you may now login</a>.<a href=login.php>Click Here to Login</a></p>

<?php
}
else
{
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<table border="0">
<tr><td>Username:</td><td>
<input type="text" name="username" maxlength="60">
</td></tr>
<tr><td>Password:</td><td>
<input type="password" name="pass" maxlength="10">
</td></tr>
<tr><td>Confirm Password:</td><td>
<input type="password" name="pass2" maxlength="10">
</td></tr>
<tr><th colspan=2><input type="submit" name="submit" value="Register"></th></tr> </table>
</form>

<?php
}
?>

</body>
</html>

This is my login script:

<html>
<head>

<title>untitled</title>

<?php
// Connects to your Database
mysql_connect("mysql", "username", "password") or die(mysql_error());
mysql_select_db("Users") or die(mysql_error());

//Checks if there is a login cookie
if(isset($_COOKIE['ID_my_site']))

//if there is, it logs you in and directes you to the members page
{
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$checkusername = mysql_query("SELECT username FROM Users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check ))
{
if ($pass != $info['password'])
{
}
else
{
header('Location: home.html') ;
}
}
}

//if the login form is submitted
if (isset($_POST['submit'])) { // if form has been submitted

// makes sure they filled it in
if(!$_POST['username'] Ś !$_POST['pass']) {
die('You did not fill in a required field.');

}

// checks it against the database

if (!get_magic_quotes_gpc()) {
$_POST['email'] = addslashes($_POST['email']);
}
$checkusername = mysql_query("SELECT username FROM Users WHERE username = '$username'")or die(mysql_error());

//Gives error if user dosen't exist
$check2 = mysql_num_rows($checkusername);
if ($check2 == 0) {
die('That user does not exist in our database. <a href=reg.php>Click Here to Register</a>');
}
while($info = mysql_fetch_array( $check ))
{
$_POST['pass'] = stripslashes($_POST['pass']);
$info['password'] = stripslashes($info['password']);
$_POST['pass'] = md5($_POST['pass']);

//gives error if the password is wrong
if ($_POST['pass'] != $info['password']) {
die('Incorrect password, please try again.');
}
else
{

// if login is ok then we add a cookie
$_POST['username'] = stripslashes($_POST['username']);
$hour = time() + 3600;
setcookie(ID_my_site, $_POST['username'], $hour);
setcookie(Key_my_site, $_POST['pass'], $hour);

//then redirect them to the members area
header('Location: home.html') ;
}
}
}
else
{

// if they are not logged in
?>
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
<table border="0">
<tr><td colspan=2><h1>Login</h1></td></tr>
<tr><td>Username:</td><td>
<input type="text" name="username" maxlength="40">
</td></tr>
<tr><td>Password:</td><td>
<input type="password" name="pass" maxlength="50">
</td></tr>
<tr><td colspan="2" align="right">
<input type="submit" name="submit" value="Login">
</td></tr>
</table>
</form>
<?php
}

</body>
</html>

I think I can't redirect to the home page in a php script that has html tags? So how do I this? Please review my script and tell whats wrong? Thanks!
