Works in IntelliJ, but I get a Bummer: Compilation Error when trying to submit

When I run this code locally it it compiles and works with no issues. When I try to submit the code in during the challenge, it says there's been a compilation error. Does anyone have any ideas why that may be? Thanks in advance!

#  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
