hey guys,

i`m new at php and codeigniter. i`ve a question.
i get this error message.

Code:

Fatal error: Call to undefined method CI_Loader::libary() in D:\xampp\htdocs\chris\application\controllers\login.php on line 36

line 36 in my php file:

Code:

function create_member()
    {
        $this->load->libary('form_validation');
........

in my autoload.php i`ve loaded the form_validation libary

Code:

$autoload['libraries'] = array('database', 'session', 'form_validation');

so whats the error because i`ve loaded the form_validation libary or?
