So I've finished the TODO's, everything seems to be working, the output prints out the story, but I still get an error "Bummer! Looks like you didn't present the TreeStory(3)!" What am I missing?

prompt.run(template);

# This is essentially what I am testing
1. The user is prompted for a new string template (the one with the double underscores in it).
a. The prompter class has a new method that prompts for the story template, and that method is called.
2. The user is then prompted for each word that has been double underscored.
a. The answer is checked to see if it is contained in the censored words.
User is continually prompted until they enter a valid word
3. The user is presented with the completed story

Courses Plus Student 9,193 PointsNever mind, all I needed is to let the user type in his own story and it worked.
