i made a rock paper scissors program myself. i havent worked on it in a while, and its very primitive and unclean. ill post it for you and you can compare it to yours if you want. i dont care what you do, its basically a skeleton, but you should thank me for it (and by thank i mean click the "this post was helpful" button so i look like i actually contributed to the forums) lol

I attempted to fix your code however there is so much going on i got lost lol

rember to use { and } to make your if and if else statements clear. I really had no idea what you were doing.

Congatulations! However, this topic is 2 years old and I don't think the OP will be coming back anytime soon.
