NetLogo: Monitor variable of turtle

I have a breed "robots" and I create a single robot with health 0.

breed [robots robot] 
create-robots 1 [
  set health 0
]

Now I want to track the robot's health during runtime. I've tried many things like

[ health ] of robot 0

But it just doesn't seem to work, the monitor just shows "N/A" like below.

enter image description here

Any idea?

There's nothing wrong with your code (or the bit you've shown anyway). Have you actually run the procedure that the create is inside of? Here's is a complete model:

breed [robots robot]
robots-own [health]

to setup
  create-robots 1
  [ set health 0
  ]
end

If you have a monitor with [ health ] of robot 0 it will show N/A initially. As soon as you run the setup procedure (with a button call, or from the command center), it changes to 0.
