Now we need to output HTML <p> elements with the name attribute of each pet. Within the each block, add <p></p> HTML tag

Not sure where I'm wrong.. If someone could please explain why I was wrong it'd be greatly appreciated.

app/views/pets/index.html.erb 
<% @pets.each do |name| %>
  <p>
    <%= pet.name %>
  </p>
<% end %>

The name you used for your each block's parameter doesn't match the name of the variable you're accessing within the each block:

<!-- The next line stores each pet in a variable called "name" -->
<% @pets.each do |name| %>
  <p>
    <!-- The next line accesses a nonexistent variable called "pet" -->
    <%= pet.name %>
  </p>
<% end %>

Change it to @pets.each do |pet|, and it should work.

If you haven't already done our Ruby Loops course, you may find some helpful info here.

That didn't seem to work for me. I had a look back at previous videos and it just didn't make sense.

I passed the challenge by changing the parameter to title and the embedded Ruby to title.name though.. could it be a bug?

Stefan Piatkov I was able to pass the challenge using this code:

<% @pets.each do |pet| %>
  <p><%= pet.name %></p>
<% end %>
