and checklogin.php is

<?php

 $host="localhost"; // Host name 
$username="root"; // Mysql username 
$password=""; // Mysql password 
$db_name="map_my_way"; // 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 
$username=$_POST['username']; 
$password=$_POST['password']; 

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

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

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

// Register $username
$_SESSION['login'] = true;
$_SESSION['username'] = $username;
header("location:user_index.html");

}
else {

echo "Wrong Username or Password";
}
?>

You need session_start() at the top of all scripts that intend to use the session state, whether to read from or set it.
Adding session_start() to your checklogin.php should fix the problem.
