Check if bool is true then run script?

How can i make it spawn a object when the bool state is true? i have it set up but it is not working why? this is C# script.

 using UnityEngine;
 using System.Collections;
  
 public class cointopon : MonoBehaviour
 {
  
   public Transform[] spawnPoints;
   public GameObject[] enemyPrefabs;
   public float amountEnemies = 20;  // Total number of enemies to spawn.
   public float yieldTimeMin = 0;
   public float  yieldTimeMax = 5;  // Don't exceed this amount of time between spawning enemies randomly.
   public int i;
   public bool state;
  
     void Update() {
     yieldTimeMin =  PlayMakerGlobals.Instance.Variables.GetFsmFloat("coinboolmin").Value;
     yieldTimeMax =     PlayMakerGlobals.Instance.Variables.GetFsmFloat("coinboolmax").Value;
     amountEnemies = PlayMakerGlobals.Instance.Variables.GetFsmFloat("coinboolamount").Value;
     state= PlayMakerGlobals.Instance.Variables.GetFsmBool("coinbool").Value;
     }
     
   public IEnumerator Spawnblock() 
   { 
      if (state == true) {
       for (i=0; i<amountEnemies; i++){
             
         var randNum = Random.Range(0, spawnPoints.Length);
         yield return new WaitForSeconds(Random.Range(yieldTimeMin, yieldTimeMax));  // How long to wait before another enemy is instantiated.
  
         var obj = enemyPrefabs[Random.Range(0, enemyPrefabs.Length)]; // Randomize the different enemies to instantiate.
         var pos = spawnPoints[randNum];
  
         Instantiate(obj, pos.position, pos.rotation); 
       }
   }
  
 }
 }
