Page goes blank on submit

[WAMFT1]

I have a problem that when I submit the page goes blank or goes to the location specified in header but it does not update the sql record. This used to work but I made some changes and now I cannot get it back. Any assistance would be appreciate.

<?php
require('edb.php'); 
$id=$_REQUEST['id'];
$ActivateCode=$_REQUEST['ActivateCode'];

$result=mysql_query("SELECT * FROM `eusers` WHERE id = '$id' && ActivateCode = '$ActivateCode'");
$test=mysql_fetch_array($result);
if (!$result) 
		{
		die("Error: Data not found..");
		}
	$id=$test['id'];
	$FirstName=$test['FirstName'];
	$LastName=$test['LastName'];
	$State=$test['State'];
	$Username=$test['Username'];
    $Password=$test['Password'];
	$Email=$test['Email'];
	$Active=$test['Active'];
	$SecurityCode=$test['SecurityCode'];
    $AdviserCode=$test['AdviserCode'];
	$UserType=$test['UserType'];
	$ActivateCode=$test['ActivateCode'];
	
	if(isset($_POST['Submit']))
{	
	$Password_save =sha1($_POST['Password']);
	$Email_save =$_POST['Email'];
	$Active_save =$_POST['Active'];
	$SecurityCode_save =$_POST['SecurityCode'];
	$ActivateCode_save =$_POST['ActivateCode'];
			
mysql_query("UPDATE `eusers` SET Password ='$Password_save', Email ='$Email_save', Active ='$Active_save', SecurityCode ='$SecurityCode_save', ActivateCode ='$ActivateCode_save' WHERE id ='$id'")
					or die(mysql_error("Did not Save")); 
	echo "Saved!";
	header("Location: index.php");			
			}
?>

Your code doesn't have error checking logic in it. Turn on the error_reporting functions on the top of this file!

Also, you can show us the HTML form.
