Hot to use walking animation while aiming!

Hi, I currently want to use a walking animation while aiming, I use a script for aiming (not done by me) which translates the weapon to the aiming position when right click is held, but I cant seem to get both working together. any help. This is the code.

 var applymode : boolean;
  
 var ObjectToMove: GameObject; 
  
 var smoothTime : float = 1.0f;
  
  
 var PositionX : float;
  
 var PositionY : float;
  
 var PositionZ : float;
  
  
 var StartPos: Vector3;
  
  
 function Start(){
  
   StartPos = transform.localPosition;   
  
 }   
  
 function Apply()
 {
  
  
     var targetPosition : Vector3 = Vector3.Lerp(ObjectToMove.transform.localPosition, Vector3(PositionX,PositionY, PositionZ), Time.deltaTime * smoothTime);
  
  
  
     ObjectToMove.transform.localPosition = targetPosition;
  
 }
  
 function ApplyOff()
 {
    applymode = false;
   var targetPositionRes : Vector3 = Vector3.Lerp(ObjectToMove.transform.localPosition, StartPos, Time.deltaTime * smoothTime);
      ObjectToMove.transform.localPosition = targetPositionRes;
  
 }
  
  
 function Update () {
  
     if(Input.GetMouseButtonDown(1) && applymode == false){
        applymode = true;
        Apply();
     }
  
      if(Input.GetMouseButtonUp(1)){
        applymode = false;
  
     }
    if(!applymode){
     ApplyOff();
    }
  
  
  
  
  
     if(applymode){
  
        Apply();
     }   
  
 }
