problem come

I donno where should i post this msg...sorry if i have posted in wrong place...:)

I have problem with frameset design. When i click on a link on left frame named leftFrame,
the login screen will appear in the main frame called mainFrame. But after i login sucessfully, the menu somehow appear in the MAIN FRAME. It should appear in the leftFrame as i set target="leftFrame".

I use javascript window.location. as follwing:

if( strcmp( $ValidPassword[1], $txtPassword) == 0 )
{
 
$complete = 1;
            $userid = $txtUserID;
session_register('userid');
            $HTTP_SESSION_VARS['userid'] = $userid;

           
?>
            <script language ="JavaScript">
              window.location = "cust_menu.php";
                </script>";
<?php
}else

blah blah blah


everthing work well except WHY the frameset got this kind of problems? By default, the left frame have two links: customer login, staff login. Once the user click the link, the login form appear well in the mainframe, but after log in, the menu display on the wrong location. it display on the mainFrame and not on the leftFrame as i want. How to solve this poblem?
