You need to decide whether you are using arcade drive or tank drive (or something else). For arcade drive, you need to open up the arcade drive vi and wire in the joystick you will use and such. For tank drive, use the tank drive vi and open 2 joysticks. Wire the ONLY the y axes of the joysticks to the tank drive axes inputs. It's probably a little difficult to read this, but I hope this helps!
