I am getting an odd error message for TreeStory

I have tested this in the IDE and it ran OK. I think that I did not account for whatever test they used. However, I am not sure how to do that. I just know that I cannot get to TreeStory 3 or whatever.

Anyway, the error message is: Use double underscores '' to surround the words in wish you want to prompt for. Enter Your Story: Please write a Testing __first prompt and then second prompt: Please write a first prompt: Be nice, try another word for first prompt Be nice, try another word for first prompt Please write a second prompt: null We cannot compare the words to the censored words entry. Your TreeStory:

Testing PASS_2 and then null

#  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

In the try/catch block, you are prompting for a single word but passing the entire story as a phrase. You don't need to call promptForWord() yourself because the run() method will do that for you. Try it with removing the entire try/catch block and just call prompt.run(tmpl);
