Login with roles does not work

I have the following problem:

I am creating a login in which 2 types of users (Admin and Client) can enter. But for some reason, the PHP entry form of the client does not work for me, I have changed the type of login and many times, with different variables, different ways of doing it, etc; and even then I can not make it work in a good way.

I clarify that I am new to this. Could anyone help me? Thanks in advance.
