how to make multiple purchase buttons in just 2 scripts?

I am trying to make a 2d clicker game and am unsure on how to make multiple purchase buttons without there being an error. In my game, I already have a purchase button up and working, but when i duplicate the scripts to make a second, it does not work. So, i decided to put the different varibles into one script but that also does not work for me. As for my scripts, i have a seperate one defining my variable you are to purchase, so it goes by global. For example, (GlobalBaker). All I really need to know is how to add multiple variable into these scripts known as, PurchaseLog and AutoFloppa. I already have the global script set up for my new purchase button and it is called GlobalFloppaFamily. So, how would i seperate these variables into my 2 scripts so that it works properly? My first purchase button and global is also displayed in these scripts.

PurchaseLog Script:

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

public class PurchaseLog : MonoBehaviour {

 public GameObject AutoFloppa;
 public AudioSource playSound;

 public void StartAutoFloppa() 
 {
     playSound.Play();
     AutoFloppa.SetActive(true);
     GlobalFloppaCash.FloppaCashCount -= GlobalBabyFloppa.babyfloppaValue;
     GlobalBabyFloppa.babyfloppaValue *= 2;
     GlobalBabyFloppa.turnOffButton = true;
     GlobalBabyFloppa.babyfloppaPerSec += 1;
     GlobalBabyFloppa.numberOfBabyFloppa +=1;
 }

}

AutoFloppa Script:

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

public class AutoFloppa : MonoBehaviour {

 public bool CreatingFloppa = false;
 public static int FloppaIncrease = 1;
 public int InternalIncrease;

 void Update () {
 FloppaIncrease = GlobalBabyFloppa.babyfloppaPerSec;
 InternalIncrease = FloppaIncrease;
 if (CreatingFloppa == false)
 {
     CreatingFloppa = true;
     StartCoroutine(CreateTheFloppa());
 }

}

IEnumerator CreateTheFloppa () { GlobalFloppa.FloppaCount += InternalIncrease; yield return new WaitForSeconds (1); CreatingFloppa = false; } }
