Refnum Defining

[Pausert]

I'm having difficulty with having my sensors read to my front panel. I know that the sensors function because they work in the front panel of the example VIs for digital inputs. I've managed to find an error message that tells me that the refnum I'm calling for my "get" statement does not exist. I had thought that I had created the refnum because I followed these instructions:

1. In the Project Explorer window of the FRC robot project, within the
Team Code folder under the RT CompactRIO Target, double-click
the Begin.vi item to open the Begin VI.
2. Select Window»Show Block Diagram or press the <Ctrl-E> keys to
view the block diagram.
Notice that references have already been set for Camera, Watchdog,
Left and Right Motors, and Joystick 1.
3. Add a Gyro Open VI to the block diagram below the Joystick 1 reference.
4. Right-click the Analog Input terminal of the Gyro Open VI and select
Create»Constant from the shortcut menu.
5. Add a Gyro RefNum Registry Set VI to the block diagram to the right
of the Gyro Open VI.
6. Right-click the refnum name input of the Gyro RefNum Registry Set
VI and select Create»Constant from the shortcut menu.
7. Type the name you want to assign to this reference, such as Gyro 1.
8. Wire the GyroDevRef output of the Gyro Open VI to the GyroDevRef
input of Gyro RefNum Registry Set VI.
9. Wire the error out output of the Gyro Open VI to the error in input
of the Gyro RefNum Registry Set VI.

Is there some other step or setting for creating a refnum?
