Max Kohl guessing game

The only spec I haven't fully completed yet is outputting an error and not using up a guess. Right now it will successfully check if the number is out of the (1..10) range, but I can't get the guess counter loop to run all the way through. This error only happens when an out-of-range number is guessed; if a number within the (1..10) range is entered, the program runs perfectly (at least, to my knowledge so far!)
