This is a good question.

The "Port" is referring the port in which you have your Joystick connected to.

The "Axis" is referring to which axis of the joystick you'd like to use.

You need to set the "Port" for the joystick you are using, and the "Axis" for the axis you'd like to use (it says, 1=x-axis, 2=y-axis, and so on.)

Hope this helps,
