Solved I guess thanks for your time!
See I told you there would be an explanation.
As far as pin numbers, analogRead() expects a either a value from 0 to 5 (on a 328p based board) or the alias defined values of A0 to A5. So while you can use a analog pin as a digital pin using a digitalRead() command using pin numbers 13 to 19 you can't use numbers 13 to 19 with a analogRead() command. It's just how they wrote those functions to work.
