HiIt sounds as if you do not have the MFRC522 Libraries installed, you can get these from "git hub". Do a search for MFRC522.

HiSorry for the delay, the code has now been sorted out for you with the #includes now added.The problem occurred when I copied the code from Arduino IDE and I had not realised that it had not copied correctly.I hope you enjoy the project
