Thanks again. I have no idea what I was doing wrong. Maybe I was just being impatient. But now it is working a treat, and all I did was plug the USB in and start working as normal. I am learning a ton and you guys are being very patient with me. I promise to repay in the future.
BTW, I have finished my first game and I want to put it on the family phones. I'm actually quite impressed with my efforts, although I know already that it is agricultural and I will rewrite it in the future. I'm reading all about how I should have used arrays etc.
