[Solved] Get Instance Not Working In Library

When I submit my form codeigniter get instance CI not working. Throws error below? I use HMVC.

Severity: Notice
Message: Undefined variable: CI
Filename: libraries/User.php
Line Number: 17

Line 17 is $input_password = $CI->input->post('password');

Any ideas on whats wrong with library?

I got it working couple things I missed spelled in on of the config settings.

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!

I don't know how you got it working, but $CI should be $this->CI everywhere you're using it since CI is a property of your class.
$input_password = $this->CI->input->post('password');

@CroNiX I have now updated it your way and works even better.
