What is the best way to echo out error messages from the Controller to the View

[eluser]Namsu[/eluser]
In my controller I have:

else {

$data = array( 'errors' => 1 );
$this->load->view('yascms/login', $data);

}

and in my view I have the line:

<?php if (isset($errors) && $errors == 1) { echo "Credentials invalid, your IP Address is logged"; }; ?>

I have a blank page. Not sure what is wrong with this code. If you can help me out that would be great.
