Hi Im getting an core error which is really standard I suppose in Ruby but dont know what to make of it. I have a program that I have written. Its purpose is to register guests at a camping. You have a menu with 5 different options. 1. Checkin. When i do this I get a undefined method generateParkingLot' for #<Camping:0x10030a768> (NoMethodError)
When I choose Checkout I get a undefined local variable or methoddeparture' for Menu:Class (NameError).
So please i someone has a clue to my problem it would be great. I will here paste all my code. The code is separated in different files and I have used require for the different files. Here though I will paste all the code in one trace. Thankful for all help.
