XML reading help(urgent)

Here is my xml file

<Config>
<PI>
   <Id value="1" />
   <Con>
      <Type value="text" />
   </Con>
 </PI>
</Config>

The XML file loads fine. However when I try ti access the value from the node. I get nothing. I need to get the word text from the Type. What am I doing wrong or missing.

         // Load XML document, loads into memory
         XmlDocument xmlDoc = new XmlDocument();
         try
         {
            xmlDoc.Load(sConfigFile);
         }
         catch (Exception ex)
         {
            System.Diagnostics.EventLog.WriteEntry(this.ToString(),
               "Error XML reading" + ex.ToString(),
               System.Diagnostics.EventLogEntryType.Error);
         }

         //read the document and pull the node into the Text box
         try
         {

            XmlNode TypeNode = xmlDoc.SelectSingleNode
           ("/Config/PI/Con/Type");
            string Type = TypeNode.InnerText;
            MessageBox.Show("results: " + Type, Text);
         }
         catch (Exception ex)
         {
            System.Diagnostics.EventLog.WriteEntry(this.ToString(),
               "Error XML reading" + ex.ToString(),
               System.Diagnostics.EventLogEntryType.Error);
         }
