You should post a new topic with a precise explanation of what you have done (either post your capx or at least a screenshot of your code), what you are expecting this current code to do and what you are actually experiencing.
I don't understand what you mean by "Counting mistakes hitting the wrong key", it doesn't make sense to me with your previous question about subtracting letters from a word.
You should rather explain the overall idea of the mechanic you are trying to implement.
