Spawn Pickups Randomly- Why aren't my variables showing up in the inspector?

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

public class FlySpawner : MonoBehaviour {

[SerializeField]
private GameObject flyPrefab;
[SerializeField]
private int totalFlyMinimum = 12; 
private float spawnArea = 25f; 
public static int totalFlies; 


// Use this for initialization
void Start () {
    totalFlies = 0; 

}

// Update is called once per frame
void Update () {

    //while there are fewer than the "total fly minimum" variable...
    while (totalFlies < totalFlyMinimum) {
    //increment flies
        totalFlies++; 
        //and create a random position for the fly to spawn at 
        float positionX = Random.Range(-spawnArea,spawnArea); 
        float positionZ = Random.Range(-spawnArea,spawnArea); 

        Vector3 flyPosition = new Vector3 (positionX, 2f, positionZ); 

        //and actually create these flies 
        Instantiate(flyPrefab, flyPosition, Quaternion.identity);
    }

}
