What do these error messages mean?

I am in section 9 of the hartl rails tutorial; this definition does not make sense. thoughts?

 Failure/Error: visit users_path
 ActionView::Template::Error:
   wrong number of arguments (2 for 1)
 # ./app/helpers/users_helper.rb:3:in `gravatar_for'
 # ./app/views/users/index.html.erb:7:in `block in _app_views_users_index_html_erb__3004047397113020476_70255017945740'
 # ./app/views/users/index.html.erb:5:in `each'
 # ./app/views/users/index.html.erb:5:in `_app_views_users_index_html_erb__3004047397113020476_70255017945740'
 # ./spec/requests/user_pages_spec.rb:12:in `block (3 levels) in <top (required)>'



2) User pages index should list each user

In your user_helper.rb file in the auxiliary folder, you pass 2 arguments instead of 1 for the gravatar_for method . If you put the code, that would be a lot easier to solve.

The first exercise in chapter 7 states that you are expanding the method gravatar_forto include a new optional parameter to include size. You probably did not complete this exercise and therefore expect only the initial 1 argument, not both arguments. Complete the exercise and you must complete this code.
