login i php

Hej alle.

når jeg prøver at logge ind på min hjemmeside skriver den bare wrong username or password
prøv selv (http://64.251.15.233/vilmand/login/main_login.php)

username (try)
password (try1234)

kan nogle hjælpe mig med hvad der er galt.

her er koden.

<?php
session_start();
$host="localhost"; // Host name
$username="vilmand"; // Mysql username
$password="vil75949"; // Mysql password
$db_name="vilmand"; // 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, $mypassword and redirect to file "login_success.php"
/*$expire=time()+60*60*24*30;
setcookie("user", $myusername, $expire);

session_register("myusername");
session_register("mypassword");
*/
$_SESSION['username'] = $myusername;

header("location:login_success.php");

}
else {
echo "Wrong Username or Password";
}
