COMPLETE multi coin tutorial RESQUEST

ok, first i appreciate that..

second i NEVER heard of "bool" i have used bytes, const ints and ints.., basically yer talking/teaching out of my league.. i am a newb to arduino.. my strong points are vb and html and ds game coding - (the app no longer)..

thirdly i don't see that within my current code to help me

fourth, the code example cannot be that short vs post 7

use my code to show me what i am doing wrong and need.. so i can work on it please
i need to see in MY code what i am missing/error wise so i can improve and better myself with it
