Unknown Identifier: 'SerializeObject'

Question

Ok I am writing a save game function and I am using this example as my baseline : http://wiki.unity3d.com/index.php?title=Save_and_Load_from_XML

problem is when I try to use it in my script the compiler does not recognize SerializeObject. It compiles the example just fine so I know I am screwing up somewhere. I would very much appreciate if someone can point out my mistake : P

I'll include the whole script since I probably forgot to import something or get something set up properly. But the function in particular that is not working is the Save() function.

My Code:

 #pragma strict

I Figured it out. I was missing a function from the tutorial:

    // Here we serialize our UserData object of myData
    //string SerializeObject(object pObject)
 function SerializeObject(pObject : Object)
 {
    var XmlizedString : String  = null;
    var memoryStream : MemoryStream  = new MemoryStream();
    var xs : XmlSerializer = new XmlSerializer(typeof(UserData));
    var xmlTextWriter : System.Xml.XmlTextWriter  = new System.Xml.XmlTextWriter(memoryStream, Encoding.UTF8);
    xs.Serialize(xmlTextWriter, pObject);
    memoryStream = xmlTextWriter.BaseStream; // (MemoryStream)
    XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
    return XmlizedString;
 }
