I can’t even get the menus to work!
I have put in some Serial debug lines and yet nothing happens!
I’m really stumped actually… but my wife is demanding i get off the computer and get ready to go lol so I would LOVE to stay and keep trying but yeh… happy wife, happy life! 
Here is my code… cleaned up slightly and added Serial debugging.
