HELP ME ON PHOTON. UNITY 3D MULTIPLAYER FPS

Hello, I just started to create FPS multiplayer games by following a tutorial made by Welton King. Link: https://www.youtube.com/watch?v=MAAxL6Q_ElE&list=PL6PsTmPNvw0eZirNDjO8dL0Y6X0ZFGaMt I am stuck at #14. Somehow when I equip the weapon, it doesn't show on another person's screen. I have the same code as video. But somehow it seems like it is not working.

         if(currentWeapon != null)

             Aim((Input.GetMouseButton(1)));
