Look Erik, I have been trying as hard as I can to make this thing to work. I do exactly everything you or anyone else posts in this forum. I am not an expert, so that is why I always follow intructions. I have been working with the code I posted here and keil's forum. I always make separate projects for every function I do not understand or does nor work properly. My name is Juan Carlos and caleno is how my friends call me. I do not post messages to waste anyone's time. I thank every one who helped me.
