My script doesnt recognize my player

Hello folks i have this script that on trigger stay, enables/disables thirdpersocontroller script on button press, it seems not to work even tho i drag and drop my Player on the gameobject spot. My project is made of 2 scenes and my Player starts on scene 0 and then when i press "START GAME" he spawns on scene 1, so when i am on scene 1 and while playing my game i drag and drop Player again on the gameobject spot and that seems to work for my script, anyone know why this is happening?? this is the script:

 var Player : GameObject;
 
 function Start () {
 }
 
 function OnTriggerStay (other : Collider)
 {
 
    if(other.gameObject.tag == "Player"){
        if(Input.GetKeyDown("2")) {
        Player.GetComponent(ThirdPersonController).enabled = true;
     }
 }
    
     else if(Input.GetKeyDown("3")) {
     Player.GetComponent(ThirdPersonController).enabled = false;
     }
 }
