Notice: Undefined index: myusername

i've been trying make a login page, but it always says

"Notice: Undefined index: myusername in C:\xampp2\htdocs\loginsession\login_success.php on line 3"

here's checklogin.php:

<?php

$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="members"; // Table name 

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password");//or die("cannot connect"); 
mysql_select_db("$db_name");//or die("cannot select DB");

// username and password sent from form 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
    $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
    $result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
    session_start();
    $_SESSION['username'] = $myusername;
    $_SESSION['password'] = $mypassword;
    header("location:login_success.php");
}
else {
    echo "Wrong Username or Password";
} ?>

and here's login_success.php:

<?php
session_start();
if($_SESSION['myusername']){
header("location:main_login.php");
}

?>

change

if($_SESSION['myusername']){

to

session_start();
if(isset($_SESSION['username'])){

There is typo: (username x myusername)

<?php
session_start();
if($_SESSION['username']){
    header("location:main_login.php");
}
