        string[] parts = line.Split(',');

        string id = parts[0];
        int score = int.Parse(parts[1]);


        if (!fbProfileImages.ContainsKey(id)) //Have we already loaded this user before?
        {
            //No, better get our image!
            WWW imageRequest = new WWW("http://graph.facebook.com/" + id + "/picture");
            yield return imageRequest;
            fbProfileImages.Add(id, imageRequest.texture);
        }

        scores.Add(id,score);            
    }                
}

}

In line 66 which is "int score = int.Parse(parts[1]);" is error array index is out of range. i've already find other similar topic but i can't slove this problem and i can't Build my project. But it's work if i put variable manually "int score = 999;" which is not the point of using split array

Please help me rewrite the code

thank you.
