the initial code you are given is:

<% @statuses.each do |status| %>
  Name: <br />
<% end %>

the above code sets up a for each loop that creates a working variable status that is available in the block. we can access that working variable status inside some embedded ruby tags. we want to access the name property of that status using name.status.

remember, since we want to insert the name into the template, we need to use erb tags that use the equals sign

<%= %>

<% @statuses.each do |status| %>
  Name: <%= status.name %><br />
<% end %>

the above code loops through every single status and prints out the name of each one

Thanks for the help, that worked! Don't know why I was stumped. Feel like I have a decent grasp of the basics for Ruby, so maybe I just need to get used to Rails.

rails and ruby are really completely different beasts. This is a good excerpt that outlines that fact from an excellent free Rails Tutorial eBook by Michael Hartl that I would recommend checking out

Rails is written in Ruby, but Rails isn’t Ruby. Some Rails classes are used like ordinary Ruby objects, but some are just grist for Rails’ magic mill. Rails is sui generis, and should be studied and understood separately from Ruby.
