Pot with my arduino should be working, but in game controller, Properties, Axis are not moving

I'm really sorry that this may be the wrong Tag.

So in the pic I have my code and the properties tab.
I used this code to check that it actaully does give a value:

Serial.print("Throttle value: "); 
  Serial.println(throttle_);

And it did between 0 and 257. But axis is still not moving. What could be the cause?

Edit:

I do have a few mistakes in the pic that I have fixed since. Its a bit old screenshot but the coding works.
