Joystick Button Name

What are the button trigger names on the VEXnet Joystick? I am trying to program them for the drive, but I don’t know the correct names. It says: 6U, and 5U. What goes in front of that, Btn?


Yes they are Btn5U.
I always have this open when I start a program.

It has all the variable names for robotc.

OK, just making sure. I just printed that page out. That helps a lot!
