View within view and validation

[eluser]Computerzworld[/eluser]
Hello. I am having one login form which is at the right side. And user can register from there. Now if user opens the registration form and submits the form without filling data it displays the error in registration form and in login form which is on the right side of registration form because of $this->validation->error_string is written in both views.Is it possible to seperate out these two error strings anyhow? If yes then please reply me. Thanks in advance.
