elevator with buttons

hello i am trying to script an elevator i want it to move to the second floor when i press the f button and to the third floor if i press the g button. I made a platform i made a first floor gameobject and a third and second floor gameobject but the problem with my script is that when i press the f button it goes to the second floor but when i add the g button scrip the f button bugs and to unbug it the g button has to be pressed so that the f button works i don't know what to do as i said i want it to go to the second floor when i press f and i want it to go to the third floor when i press g . this is my scrip

 var smooth = 2.0;
 var DestinationSpot:Transform;
 var OriginSpot:Transform;
 var up : boolean;
 var down : boolean;
 //Main function
 function Update ( ){
  if(transform.position == DestinationSpot.position)
     {
         Switch = true;
     }
     if(transform.position == OriginSpot.position)
     {
         Switch = false;
     }
 if(up == true){
 transform.position = Vector3.MoveTowards(transform.position, DestinationSpot.position, smooth);
 // Dampen towards the target rotation
 transform.position = Vector4.MoveTowards(transform.position, OriginSpot.position,
 Time.deltaTime * smooth);
 }
  
 if(up == false){
 transform.position = Vector3.MoveTowards(transform.position, OriginSpot.position, smooth);
 // Dampen towards the target rotation
 transform.position = Vector4.MoveTowards(transform.position, DestinationSpot.position,
 Time.deltaTime * smooth);
 }
  
 if(down == true){
 if(Input.GetKeyDown("f")){
 up = !up;
 }
 }
  
 }
  
 //Activate the Main function when player is near the door
 function OnTriggerEnter (other : Collider){
 
 if (other.gameObject.tag == "Player") {
 (down) = true;
 }
 }
  
 //Deactivate the Main function when player is go away from door
 function OnTriggerExit (other : Collider){
  
 if (other.gameObject.tag == "Player") {
 (down) = false;
 }
 }
 this was the first scrip this is the second
 var smooth = 2.0;
 var ThirdSpot:Transform;
 var OriginsSpot:Transform;
 var left : boolean;
 var right : boolean;
 var //Main function
 function Update ( ){
  if(transform.position == ThirdSpot.position)
     {
         Switch = true;
     }
     if(transform.position == OriginsSpot.position)
     {
         Switch = false;
     }
 if(left == true){
 transform.position = Vector3.MoveTowards(transform.position, ThirdSpot.position, smooth);
 // Dampen towards the target rotation
 transform.position = Vector4.MoveTowards(transform.position, OriginsSpot.position,
 Time.deltaTime * smooth);
 }
  
 if(left == false){
 transform.position = Vector3.MoveTowards(transform.position, OriginsSpot.position, smooth);
 // Dampen towards the target rotation
 transform.position = Vector4.MoveTowards(transform.position, ThirdSpot.position,
 Time.deltaTime * smooth);
 }
  
 if(right == true){
 if(Input.GetKeyDown("g")){
 left = !left;
 }
 }
  
 }
  
 //Activate the Main function when player is near the door
 function OnTriggerEnter (other : Collider){
 
 if (other.gameObject.tag == "Player") {
 (right) = true;
 }
 }
  
 //Deactivate the Main function when player is go away from door
 function OnTriggerExit (other : Collider){
 
 if (other.gameObject.tag == "Player") {
 (right) = false;
 }
 }

i placed them in two different javascript files after that i placed them into the same cube which is the elevator
