Hi Kat,

if I understand your question correctly the input letter and the letter inside the getCurrentProgress() method are not the same.

Inside the getCurrentProgress() you are creating a for loop that goes over every character inside the mAnswer (after converting String mHand into a character array). So you can read the code of the for loop like this:

    public String getCurrentProgress() {
        String progress = " ";
        for (char letter : mAnswer.toCharArray()) {
// assign every single character of the answer array ("-t-r-e-e-h-o-u-s-e-")
// to a variable called "letter" (not the input letter)
            char display = '-';

            if (mHits.indexOf(letter) >= 0) {
         // if the "letter" from the for loop is inside mHits
                display = letter; 
         // display this letter
            }
            progress += display;
        }
        return progress;
    }

So you are not using the letter from users input. Instead you create a new variable "letter" to strore characters from mAnswer to compare them with characters in mHit. Same names but different locations.

Does it make sense?
