Adding States code challenge

Hey there. I'm on the Building Social Features in Rails > Managing Friendships > Adding States code challenge 2/2. The challenge is "Call the "block_mutual_friendship" method after the transition to the blocked state."

Right now, my code is

class UserFriendship < ActiveRecord::Base
  belongs_to :user
  belongs_to :friend, class_name: 'User', foreign_key: 'friend_id'

  state_machine :state, initial: :pending do
   after_transition on: :block, do :block_mutual_friendship
    state :requested
    state :blocked
  end
end

After reading forum posts from months ago, I see that you don't need the exclamation mark like in the video, but even though I don't have that, it still says I'm wrong somehow.

Ah ok. Where in the code would I put those? Around block_mutual_friendship?
