Spawn player and scale

Hi, i'm a beginner and this is my script for spawn player. Whit this script i can spawn player, choose if i want to scale and choose if i want to spawn two player.

the actually situation is: -choose scaled -set value -play game -play the game with player scaled -stop the game -deselect scaled -play the game -play the game with player scaled -stop the game -play the game -play the game with normal player

this i what i want: -choose scaled -set value -play game -play the game with player scaled -stop the game -deselect scaled -play the game -play the game with normal player

What is the problem?

using UnityEngine; using System.Collections;

 public class SpawnPlayer : MonoBehaviour {
 
     public GameObject collectorPrefab;
     public bool multiplayer = false;
     public bool scaled = false;
     public float scale = 1f;
     
 
 
     void SpawnMultiPlayer1()
     {
         Instantiate(collectorPrefab);
         collectorPrefab.transform.position = new Vector3(-5, 12);
         collectorPrefab.transform.localScale = new Vector3(2, 2);
         if (scaled == true)
         {
             //store scale of this transform in temporary variable
             Vector2 temp = transform.localScale;
 
             //change the values for this saved variable (not actual transform scale)
             temp.x = scale;
             temp.y = scale;
 
             //assign temp variable back to transform scale
             collectorPrefab.transform.localScale = temp;
 
             collectorPrefab.transform.localScale += new Vector3(temp.x, temp.y);
         }
 
     }
