Problems redirecting to index page after logining

Im using the sever behaviors built into dreamweavers for the login function.  The directory folder location is actually dragteck.com/prismV2.  But I have it set up as a subdirectory on yahoo.  

It looks like the main problem is coming from the form submit button.  It is the only thing that is pointing to the directory.

Im not exactly sure how to fix this, since dreamweaver created the code.

Are you able to post the code?

not realy cause its a dreamweaver generated code and its not all in one place. I was wondering if there something maybe in the settings that i might need to change to fix this or if there are any special instructions for dealing with yahoo subdirecories

no i dont' think so, I have not ever had to use dm's generated code since I wrote my own login codes, however i think there is something in the code which references to the directory instead of the root. If you look through the code you should be able to find it?

I think this is the entire code but I don't see anything calling to that specific directory:

<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['username'])) {
  $loginUsername=$_POST['username'];
  $password=$_POST['password'];
  $MM_fldUserAuthorization = "level";
  $MM_redirectLoginSuccess = "index.php";
  $MM_redirectLoginFailed = "registration.php";
  $MM_redirecttoReferrer = true;
  mysql_select_db($database_prism, $prism);
        
  $LoginRS__query=sprintf("SELECT user, password, level FROM user WHERE user='%s' AND password='%s'",
  get_magic_quotes_gpc() ? $loginUsername : addslashes($loginUsername), get_magic_quotes_gpc() ? $password : addslashes($password));
   
  $LoginRS = mysql_query($LoginRS__query, $prism) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
   
    $loginStrGroup  = mysql_result($LoginRS,0,'level');
   
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;           

    if (isset($_SESSION['PrevUrl']) && true) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];      
    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

>>$_SESSION['PrevUrl'] = $_GET['accesscheck'];

where is $_GET['accesscheck'] coming from? check its value.
