A little support request.

This is very nice module, everyone would love to use.

I have a very little problem, don't know if its worth posting here.

I want user to be redirected on the front page when the username/password he/she entered is/are wrong, but any how I could not do it.
The code I wrote in login destination configuration is as follow:

 global $user;
  if ($user->uid == 1) {
    return ''; 
  }
 elseif ($user->uid > 0) {
    return 'mymondo';
 }
else {
   return "node";
}

is there any way to get rid of it?

Thank you.
