Need some help with strange situation

[SpencerH]

I have been working through writing a program for about a week now. Suddenly my inputs changed. I'm not sure why, but it has taken me down a different path. How can I write a test that gives my program both input types then will let me code to satisfy both requirements?

I guess this is like unit testing but I have not done any coding like that since college, and that was with Ruby on Rails which gave a continuous output and pass or fail message.

--- Yeah I don't even remember how I made that.

Any nudging in the right direction would be greatly appreciated. I would also be willing to pay a little if someone would spend some time with me walking me through my problem.

Thanks
