The value of register can not be a variable. You must statically define it such as:

register: cange

Additionally, ‘register’ works a little differently with loops such as with\_items. See \<[http://docs.ansible.com/playbooks\_loops.html#using-register-with-a-loop](http://docs.ansible.com/playbooks_loops.html#using-register-with-a-loop)\>
