 var PlayerMotor : CharacterMotor;
 var WalkingSpeed : float = 6;
 var SprintingSpeed : float =8;
 var PlayerBossController : CharacterController;
 var CharacterVelocity;
 var CharacterMag;
 var PlayerAimingInSpeed : float = 0.2;
 function Start () {
 
 }
 
 function Update () { 
 PlayerAnims(); 
 PlayerStateController(); 
 CharacterMag = PlayerBossController.velocity.magnitude;
 
 }
 
 function PlayerStateController () { if(Input.GetAxis("Vertical") || Input.GetAxis("Horizontal")) {
  if(Input.GetButton ("Sprint")&&!Input.GetMouseButton(1)) { 
  PlayerState = 2; 
  } 
  else if (Input.GetMouseButton(1)&& !Input.GetButton ("Sprint")) { 
  PlayerState = 3; 
  } 
  
  else { 
  PlayerState = 1; 
  } 
  } 
  else { 
  PlayerState = 0; 
  } 
  }
 
 function PlayerAnims () { 
 if(PlayerState == 0) { 
 PlayerAnimSec.animation.CrossFade("idle_animation", 0.4);
  } 
 
 else if (PlayerState == 1) { 
 PlayerAnimSec.animation.CrossFade("walking_animation", 0.4);
 PlayerAnimSec.animation["walking_animation"].speed = CharacterMag/WalkingSpeed;
 
 
 
 PlayerMotor.movement.maxForwardSpeed = WalkingSpeed ;
 PlayerMotor.movement.maxBackwardsSpeed = WalkingSpeed/2; 
 PlayerMotor.movement.maxSidewaysSpeed = WalkingSpeed ;
 
 
 
 
 }
 
 
   else if (PlayerState == 2) { 
   
   PlayerAnimSec.animation["sprint_animation"].speed = CharacterMag/SprintingSpeed;
   
   PlayerAnimSec.animation.CrossFade("sprint_animation",PlayerAimingInSpeed); 
   
 PlayerMotor.movement.maxForwardSpeed = SprintingSpeed ;
 PlayerMotor.movement.maxBackwardsSpeed = SprintingSpeed/2;
 PlayerMotor.movement.maxSidewaysSpeed = SprintingSpeed ;
 
   
   }
   
   
      else if (PlayerState == 3) { 
   
   PlayerAnimSec.animation["aiming_idle"].speed = CharacterMag/SprintingSpeed;
   
   PlayerAnimSec.animation.CrossFade("aiming_idle",PlayerAimingInSpeed); 
   
 PlayerMotor.movement.maxForwardSpeed = SprintingSpeed/0.8 ;
 PlayerMotor.movement.maxBackwardsSpeed = SprintingSpeed/0.3;
 PlayerMotor.movement.maxSidewaysSpeed = SprintingSpeed/0.8 ;
 
   
   }
      }

Help please!!!
