The Bummer! Looks like you didn't present the TreeStory (3), doesn't make sense. I did present it. Could you explain me?

Presenting TreeStory (3) is covered in Main.java line 33 and Prompter.java line 60.

Honestly, I am not sure if I understand the content of that error message or the task I am supposed to do.

    public static void main(String[] args) {

        Prompter prompter = new Prompter();

        try {
            prompter.promptStory();
        } catch (IOException e) {
            e.printStackTrace();
        }

        String finalString = prompter.run();

        prompter.presentStory(finalString);

    }

#  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

The following seems to work. I was going to replace your code bit by bit with that of a user who was able to complete the challenge (https://teamtreehouse.com/community/finishing-treestory-maybe-i-have-the-wrong-idea-of-implementation), but the first method i copied (promptForWord) made the problem go away. weird but it spared me a fun game of find the glitch.

A lot of people have been beating their heads against this particular brick wall. I think the verification for this task is very specific (and possibly based on output). If you get stuck, i think there is a way to use tagging to get treehouse to notify craig dennis. He's pretty good at rescuing his students.

yeah, I copied the screen output from successful code. I put each line inside a println in main method. I was able to pass the challenge. So verification is string comparison. Anyhow, i did notice that your output ended with

The TreeStory is:

Testing pass_1 and then pass_2

whereas the correct code ended with:

The TreeStory is:

Testing PASS_1 and then PASS_2

so it's probably that you returned the lower case word, rather than using it for testing and returning the entered word in its original case.

Thank you so much, It worked. I was beating my head with this wall.
