Actually the 'click_button' is applied to the sites home page. Once clicked I am redirected to the sites login page, where the field values are set, and 'submit' is applied. The problem that I seem to be having, is the redirection back to the login page with acceptance of the user field and denial of the password field. I'm afraid I may be missing something simple. Could it be that I have to set a field 'type' for the password?
