I'm expected to create a guessing game where the computer generates a random number and raises/limits the upper/lower bounds accordingly when generating its guess of said number. when it finally guesses it, it should break the code and end.

however, I'm having an error message stating that the "bound must be positive", which is confusing as I don't see where it would have the bound be negative as the lower bound should always be smaller then the larger bound.

thanks for any help.
