problem with radio in sunfounder crawling quadruped robot kit

hello, i’m getting mad, i need help.
i’m building this kit but when i reached the receiver fase, i got a big problem, at first a bug with the library, next a bug with “if”, now my radio results not available, this is the code

  • Overview
  • This project was written to test nRF24l01 module. If it runs, arduino will
    receives data from another transceiver with 2 Analog values from a Joystick
    or 2 Potentiometers Displays received values on Serial Monitor.

and this is the trasmitter

i hope you could help me… :o

Do you have a bootloader question?
