บรรทัด $_SEESION["CustomerID"] = $objResult["CustomerID"]; ทำไมมันไม่เอา CustomerID จาก database

<?

	session_start();

	$Username = trim($_POST["txtUsername"]);
	$Password = trim($_POST["txtPassword"]);
	
	//*** Check Username ***//
	if(trim($Username) == "")
	{
		echo "<font color=red>**</font> Plase input [Username]";
		exit();
	}
	
	//*** Check Password ***//
	if(trim($Password) == "")
	{
		echo "<font color=red>**</font> Plase input [Password]";
		exit();
	}
	
	$host = "localhost";
	$user = "root";
	$pass = "123456";
	$db = "otop";

	$objConnect = mysql_connect($host,$user,$pass) or die("Error Connect to Database");
	$objDB = mysql_select_db($db);


	//*** Check Username & Password ***//

	$strSQL = "SELECT * FROM Customers WHERE UserName = '".$Username."' and Passwords = '".$Password."' ";
	$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
	$objResult = mysql_fetch_array($objQuery);
	
	
	if($objResult)
	{
		echo "Y";

		//*** Session ***//
		$_SESSION["Username"] = $Username;
		$_SEESION["CustomerID"] = $objResult["CustomerID"];
		session_write_close();
	}
	else
	{
		echo "<font color=red>**</font> Username & Password is wrong";
	}

	mysql_close($objConnect);
?>
