Varriables not showing in Inspektor(but in Debug.Log)

Hi guys,
I have a problem.I have 3 public float Varriables but dont sow up in inspector.if i change them

public float x;
public float y;
public float z;

public void Change(float xa,float ya,float za){
x = xa+1;
y =ya+1;
z = za+1;
Debug.Log(x);
Debug.Log(y);
Debug.Log(z);
}

The Editor window doesn’t always update “live” when the game is running. You can press pause and it should update then.

thanks
i found a second promblem i used Prefabs
