BCE0019 error

Hey! Ive looked up similar threads but cant really make it fully work for my project since Im fairly new. I keep getting these errors, even tho the guy that made this script for me didnt have these issues on his computer, the exact same scene/test project, so Im at a dead end and appreciate any help. The error are:
Scripts/Joystick.js(127,27): BCE0019: 'xMove' is not a member of 'Object'.
Scripts/Joystick.js(128,27): BCE0019: 'yMove' is not a member of 'Object'.

and in another script also:
Scripts/Jumping.js(17,27): BCE0019: 'm_Jumping' is not a member of 'Object'.
Scripts/Jumping.js(18,24): BCE0019: 'tapCount' is not a member of 'Object'.

The player script is in C# unlike the others scripts in the scene, if that is of any help.
The code for Jumping.js is:

  var jumpButton : GameObject;

  var player : GameObject;

  var playerGravityBody;

  var jumpButtonV;

  var upwards : boolean = false;

  function Start()

  {

      playerGravityBody = player.gameObject.GetComponent("PlayerGravityBody");

      jumpButtonV = jumpButton.gameObject.GetComponent("Joystick");

  }

  function Update () {

      playerGravityBody.m_Jumping = upwards;

      if(jumpButtonV.tapCount >0 )

      {

          upwards = true;

      }

      else

          upwards = false;

  } 

And the code for Joystick.js is: (essentially based on Penelope script with tweaks)
This is the actual snippet of code it errors in case you dont want to see the entire code:

 function Update()
 {    
     //alter custom values in player script
     playerGravityBody.xMove = position.x;
     playerGravityBody.yMove = position.y;

And the entire code:
