can someone help me with a collect in order script which should reset a level if collected in the wrong order?,collect in order reset issue

I'm using this code to collect items in order but I'm missing a piece of code which resets the level if they are collected in the wrong order, can someone help me with this please.,I have a problem with my collect in order script, (see below)

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class CollectInOrder : MonoBehaviour {

 public float collectNumber; 
 public int collectLimit; 
 void OnTriggerEnter2D(Collider2D coll){ 
     if (coll.gameObject.name == "Collect" + collectNumber) { 
         Destroy (coll.gameObject); // Destroys the GameObject which collided with this.
         collectNumber++; 
         if (collectNumber >= collectLimit) {
             Debug.Log ("Woo, you collected them all!");
             ResetCollectNumber ();
         }
     }
 }

 
 public void ResetCollectNumber(){
     collectNumber = 1;
 }

}

This is what I have so far but my problem is that I'm missing a piece of code where the level would reset if you collect in the wrong order, hopefully someone can help me with this.
