How do I create multiple save files and make it work?

So I have a player high score system, but I made a new scene which is a top down version of the fps, and I want it to have a different high score then the other. I basically just duplicated the high score system I had from the other scene, changing names etc, but it seems as if it doesnt work even though it is the same as the one ive been using, how do I make it so 2 save files can be made? I cannot use playerprefs.

Here is my script to save the score:

  import System.IO;
   import System.Runtime.Serialization.Formatters.Binary;    //I know, it's a bit long eh? 
 
var fileName1 = "2dhs.data";
var ScoreAmount1 : int;
   
var HighScore1 : int;
   
function Start (){
    HighScore1 = ScoreLoad1.CompareScore1;
    ScoreAmount1 = GlobalScore.CurrentScore;
    if (ScoreAmount1 >= HighScore1){
        var bf = new BinaryFormatter ();
        var OurFile = File.Open (fileName1, FileMode.OpenOrCreate);
        bf.Serialize (OurFile, ScoreAmount1);
        OurFile.Close();
    }
}

and my script to load it:

  import System.IO;
  
var fileName1 = "2dhs.data";
var ScoreLoad1 : int;
var HighScoreDisplay1 : GameObject;
  
static var CompareScore1 : int;
  
function Start ()
{
    var bf = new BinaryFormatter ();
    var OurFile = File.Open (fileName1, FileMode.Open);
    ScoreLoad1 = bf.Deserialize (OurFile);
    OurFile.Close ();
  
    HighScoreDisplay1.GetComponent.<Text>().text = ScoreLoad1.ToString();
  
    CompareScore1 = ScoreLoad1;
}

This is all in javascript. and the scripts I am using for the other (working) high score system are just those scripts except take out all the "1"s and change 2dhs to hs. Thank you

Change the filename in this line in one of your scripts:

var fileName1 = "2dhs.data";

for example, in the second line, you change it to

var fileName1 = "2dhs2.data";

Serialising an integer is way overkill, I think you should use some easier and faster code for small save-games like yours.
Please take a look at FileManagement in the AssetStore, I’m sure you will like it.
Best regards.
