   Please correct the page width or CSS issues; lines are not wrapping properly and code lines hidden.

   Hi
   I am newbie in InfoPath 2010. I have three text fields in my form and I want to calculate average of them and show it in another text box. My fields are not grouped.
   Many thanks,
   Monika

   xnMyField = null;
   }
   catch (Exception ex)
   {

   throw new Exception(xPath + “:” + xValue + “:” + ex.StackTrace, ex);
   }

   Code for getting field values from InfoPath in code behind using VSTA in C#

   ///
   /// Gets the field value from InfoPath Form
   ///
   /// copy the xpath from the InfoPath Designer for the field values to be retrieved
   ///
   private string GetFieldValue(string xPath)
   {
   XPathNavigator xnDoc = this.MainDataSource.CreateNavigator();
   XPathNavigator xnMyField = xnDoc.SelectSingleNode(xPath, this.NamespaceManager);
   if (xnMyField != null)
   {
   return xnMyField.Value;
   }
   else
   {
   return string.Empty;
   }

   }
