Oh!! I didn't realize that you were attempting to pass a DataSet to your WebService method ... I think you neglected to mention that earlier. That's a no-no. You should be passing an XML string.

[WebMethod]
public string AnalyseMyData(string XMLCheckMe)
{
    DataSet dsCheckMe  = new DataSet();
    StringReader sr = new StringReader(XMLCheckMe);
    dsCheckMe.ReadXml(sr, XmlReadMode.InferSchema);
    dsCheckMe.AcceptChanges();

}
