Finishing TreeStory - Maybe I have the wrong idea of implementation?

Hi, this exercise has been giving me some trouble. Didn't want to have to resort to the forums, but after a lot of time searching, I can't seem to figure out what is wrong with my code. My code works in Intellij. This is the error I am getting:

Did you prompt the user for the story (1)? I didn't see the first double underscored word prompted (2).

Any help would be greatly appreciated.

#  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

Finally I figured this out. In promptForWord I just had to include the phrase that the user was prompted to replace, with printf and %s. FeelsGoodMan.
