Having Trouble accsessing a list in another Scene

Unity Engine

So in my game basically questions are read out like a classic drinking game but when i try to access my player names list in another scene it doesnt work although there clearly are names in the list. Here is a video:

if someone fixes this for me ill send them a 10 dollar amazon gift card i promise (AUD though)

this is the first script that basically inserts the names into a list of questions stored in a csv

using System.Collections.Generic;
using System.IO;
using System.Text.RegularExpressions;
using UnityEngine;
using UnityEngine.UI;

public class QuestionManager2 : MonoBehaviour
{
    public string questionFilePath = "Assets/CSV/cgm.csv";
    public List<string> questions = new List<string>();
    public Text questionText;

    private int currentQuestionIndex = 0;

    private void Start()
    {
        // Read the CSV file and add questions to the list
        using (StreamReader reader = new StreamReader(questionFilePath))
        {
            while (!reader.EndOfStream)
            {
                string line = reader.ReadLine();
                string[] fields = line.Split(',');

                if (fields.Length > 0)
                {
                    questions.Add(fields[0]);
                }
            }
        }

        // Display the first question
        DisplayCurrentQuestion();
    }

    public void OnNextQuestionButtonClicked()
    {
        // Go to the next question in the list
        currentQuestionIndex++;

        // If we've reached the end of the list, loop back to the beginning
        if (currentQuestionIndex >= questions.Count)
        {
            currentQuestionIndex = 0;
        }

        // Display the current question
        DisplayCurrentQuestion();
    }

    private void DisplayCurrentQuestion()
    {
        if (PlayerNameManager.instance.playerNames.Count == 0)
        {
            Debug.LogError("No player names loaded.");
            return;
        }

        // Replace {player} with the player names in the current question
        string currentQuestion = questions[currentQuestionIndex];
        foreach (string playerName in PlayerNameManager.instance.playerNames)
        {
            currentQuestion = Regex.Replace(currentQuestion, "{player}", playerName, RegexOptions.IgnoreCase);
        }

        // Update the question text UI element with the current question
        questionText.text = currentQuestion;
    }

}

this is my player name manager script

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

public class PlayerNameManager : MonoBehaviour
{
    public static PlayerNameManager instance;
    public List<string> playerNames;

    private void Awake()
    {
        if (instance == null)
        {
            instance = this;
            DontDestroyOnLoad(gameObject);
        }
        else
        {
            Destroy(gameObject);
        }
    }


    public void AddPlayerName(string name)
    {
        playerNames.Add(name);
        Debug.Log("Added player name: " + name);
    }
}

Hi,

I don’t really see where you initialize your playerNames List inside PlayerNameManager, which is weird : it is supposed to break at the first time your code goes to line 27., where you try to add a new player name to your list, since the list is not initialized.

If you’re doing it somewhere else, this could be where your problem is coming from.
Other than that, I suppose your code should be working fine.
