phpBB login (latest version)

[black-ops]

ok so I've been trying to make an external log in for my website (just testing around with php) and I've come across this problem.
If i log in using the database MD5 hash the log in works a charm, however if I used my own REAL password it returns false, could anyone possibly lend a hand here =/

<?php
$host="localhost"; // Host name 
$username="x"; // Mysql username 
$password="x"; // Mysql password 
$db_name="x"; // Database name 
$tbl_name="x"; // 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);
$mypassword = ($mypassword);

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and user_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_register("myusername");
session_register("mypassword"); 
header("location:user.php");
}
else {
echo "Wrong Username or Password";
}
?>

You need to MD5 the password for it to work. How about this:

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and user_password =MD5('$mypassword')";
