and the part of my controller that validates registeration
function register()
{
$this->form_validation->
set_rules('username', 'Username', 'xss_clean|required');

$this->form_validation->
set_rules('email', 'Email Address',
'xss_clean|required|valid_email|callback_email_exists');

$this->form_validation->set_rules('password', 'Password', 'xss_clean|required|min_length[4]|max_length[12]|matches[password_conf]
|sha1');

$this->form_validation->
set_rules('password_conf', 'Password Confirmation',
'xss_clean|required|matches[password]|sha1');

if ($this->form_validation->run() == FALSE)
{
$this->load->view('page/register');
}
else {
$data['username'] = $this->input->post('username');
$data['email'] = $this->input->post('email');
$data['password'] =
sha1($this->_salt . $this->input->post('password'));

if ($this->account_model->create($data) ===TRUE)
{
$data['message'] =
"The user account has been successfully created "
. anchor ('page/login', 'here') . ".";
$this->load->view('page/success', $data) ;
}
else {
$data['$error'] =
"There was a problem when creating your account.";
$this->load->view('page/error', $data);
}
}
}

when completing the registration form it should validate on my controller and call the model however for some reason its not could anyone help.
