Help please :)

Hi, I am getting another error preventing me from continuing the Java objects course. I have posted a part of the code down below where the error is located.

    public boolean promptForGuess(){
        Console console = System.console();
        boolean isHit = false;
        boolean isValidGuess = false;
        char guess = guessAsString.charAt(0);
        return mGame.applyGuess(guess);
      while(! isValidGuess) {
        String guessAsString = console.readLine("Enter a letter:  ");
        char guessAsChar = guessAsString.charAt(0);
        try {
          isHit = mGame.applyGuess(guess);
          isValidGuess = true;
        } catch(IllegalArgumentException iae) {
            console.printf("%s. Please try again.\n", iae.getMessage());
        }
      }
      return isHit;

The error is this: Cannot find symbol: char guessAsChar = guessAsString.charAt(0); symbol: variable guessAsString location: class prompter

You're using a variable guessAsString, but you haven't defined that variable anywhere in your code above. So it doesn't know what you're referring to.

Okay, that's what I thought but I looked through the video and I can't find him defining it. Thanks again and again ; )
