stuck with a loop/algorithm

Hey All, its been a while... Hope everyone is well on here.

My question is simply this, lol..

I created a little method to run fired through OnTriggerExit() to check for an equal division and if so instantiate a prefab. My current issue lies in my brain not functioning correctly and as a result I cant seem to work out how apply it in what`s happening below (which is correctly doing the job at evens) but whilst checking to see if the current value held in honeyCreated is not the same as it was the last time the method was fired.

in steps: on method run.... 1.check if honeyCreated is not at 0 1. if not at 0, then make sure throughput method only produces prefab at every even increment 3. only instantiate if the number is even but not if its the same number found at the last check. whats happening? Every time this runs its fine, until i get past the honeyCreated value storing 2. My factory on fills only every two deposits, but the trigger is there all the time. I have a funny feeling my stupidity will unfold in a majestic way once you amazing dudes get your heads on it.

Thanks for reading...method where the initial conditionals are happening below..:)

     void CheckHiveThroughput(int honeyCreated)
     {
         
         if(honeyCreated != 0)
         {
             if(honeyCreated%2 !=0)
             {
                 //moveHoney = false;
                 return;
             }
             else
             {
                 mPrefab = (GameObject)Instantiate(prefab, posToInstantiate, Quaternion.identity);
                 //moveHoney = true;
                 //mPrefab.transform.position = Vector3.Lerp (posToInstantiate, mMoveObjTo, timeStamp);    
             }
         }    
     }
 

EDIT: Here is whole script to clarify where things are coming from and how it updates the honeyCreated value outside the method im on about , by accessing a static value to update. (just testing with statics, will encapsulate later once working) :0 Thanks again, for reading this. gruffy
