Division player score ?

Unity Engine
1

Here what i’m trying to do is make the player finish the game as fast as he could to get good score.
So, I worked to make the game timer division the player score. But what i get are words “NaN” and “Infinity” inside total bar ?! here is my code.

using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class gtime: MonoBehaviour {

    public float GameTime;
    public float seconds, minutes, hours;
    public float division;
//
    public float money = 5f;
    public float stars = 8f;
    public float total = 1f;
    //

    // Use this for initialization
    void Start () {

        GameTime = 0.0f;
      
    }
  
    // Update is called once per frame
    void Update()
    { 
            if (minutes >= 2 && hours == 0 ){
                division = 2;
            }
            if (minutes >= 4 && hours == 0){
                division = 3;
            }
            if (minutes >= 6 && hours == 0){
                division = 4;
            }
       
            hours = (int)(GameTime / 3600.0f);
            minutes = (int)(GameTime / 60f);
            seconds = (int)(GameTime % 60f);

    }

    ////

    void count()    {
        total = (money + stars) / division;
    }

You never increment GameTime.
Also, you shouldn’t convert the values you assign to hours, minutes and seconds into integers if these are float variables. Either turn the variables into integers or use Mathf.Round() to round the values to floats.
