I want to make an application that will pull baseball scores from the internet and show them to me. I have the HtmlAgilityPack installed. I have tried using the following code that I got from Stack Overflow:

string Url = "http://bit.ly/1EKhMg0";

HtmlWeb web = new HtmlWeb();
HtmlDocument doc = web.Load(Url);

string scoreOne = doc.DocumentNode.SelectNodes("//*[@id=\"uid_0\"]/div[1]/div/div[3]/div/div[4]/div[2]/div/div[2]")[0].InnerText;

However, the code throws a Null Reference exception. What am I doing wrong?
