Hello guys, i need your help again. I’ve found [this][1] package, which allows to implement a simple leaderboard. The thing is that i’m getting errors(see attachments), the whole code seems right, i simply don’t get what’s wrong with it. Any help is invaluable.

using UnityEngine;
using System.Collections;

public class dreamloLeaderBoard : MonoBehaviour {
	
	string dreamloWebserviceURL = "http://dreamlo.com/lb/";
	
	public string privateCode = "";
	public string publicCode = "";
	
	string highScores;

	
	public struct Score {
		public string playerName;
		public int score;
		public int seconds;
		public string shortText;
	}
	
	public static dreamloLeaderBoard GetSceneDreamloLeaderboard()
	{
		GameObject go = GameObject.Find("dreamloLeaderboard");
		
		if (go == null) return null;
		
		return go.GetComponent<dreamloLeaderBoard>();
	}
	
	public void AddScore(string playerName, int totalScore)
	{
		StartCoroutine(AddScoreWithPipe(playerName, totalScore));
	}
	
	public void AddScore(string playerName, int totalScore, int totalSeconds)
	{
		StartCoroutine(AddScoreWithPipe(playerName, totalScore, totalSeconds));
	}
	
	public void AddScore(string playerName, int totalScore, int totalSeconds, string shortText)
	{
		StartCoroutine(AddScoreWithPipe(playerName, totalScore, totalSeconds, shortText));
	}
	
	// This function saves a trip to the server. Adds the score and retrieves results in one trip.
	IEnumerator AddScoreWithPipe(string playerName, int totalScore)
	{
		playerName = Clean(playerName);
		
		WWW www = new WWW(dreamloWebserviceURL + privateCode + "/add-pipe/" + WWW.EscapeURL(playerName) + "/" + totalScore.ToString());
		yield return www;
		highScores = www.text;
	}
	
	IEnumerator AddScoreWithPipe(string playerName, int totalScore, int totalSeconds)
	{
		playerName = Clean(playerName);
		
		WWW www = new WWW(dreamloWebserviceURL + privateCode + "/add-pipe/" + WWW.EscapeURL(playerName) + "/" + totalScore.ToString()+ "/" + totalSeconds.ToString());
		yield return www;
		highScores = www.text;
	}
	
	IEnumerator AddScoreWithPipe(string playerName, int totalScore, int totalSeconds, string shortText)
	{

		shortText = Clean(shortText);

		highScores = www.text;
	}
	
	IEnumerator GetScores()
	{
		highScores = "";
		WWW www = new WWW(dreamloWebserviceURL +  publicCode  + "/pipe");
		yield return www;
		highScores = www.text;
	}
	
	public void LoadScores()
	{
		StartCoroutine(GetScores());
	}

	
	public string[] ToStringArray()
	{
		if (this.highScores == "") return null;
		
		string[] rows = this.highScores.Split(new char[] {'

'}, System.StringSplitOptions.RemoveEmptyEntries);
return rows;
}

	public Score[] ToScoreArray()
	{
		string[] rows = ToStringArray();
		if (rows == null) return null;
		
		int rowcount = rows.Length;
		
		if (rowcount <= 0) return null;
		
		Score[] scoreList = new Score[rowcount];
		
		for (int i = 0; i < rowcount; i++)
		{
			string[] values = rows*.Split(new char[] {'|'}, System.StringSplitOptions.RemoveEmptyEntries);*

  •  	Score current = new Score();*

  •  	current.playerName = values[0];*

  •  	current.score = 0;*

  •  	if (values.Length > 3) current.shortText = values[3];*

_ scoreList = current;_
* }*

* return scoreList;*
* }*

* // Keep pipe and slash out of names*

* string Clean(string s)*
* {*

Try checking if

`

if(string.IsNullOrEmpty(this.highScores)) return null;

`

instead of
`

if (this.highScores == "") return null;
