Transform XML via XSL and save as XML

Hi All,

I'm attempting to save the xsl processors output back into XML, however when it gets to the save method it bombs out saying:

Object required: 'xmlNewDoc'.

Also I have dumped the contents of the output in the html and it works fine and the output I wanted is correct. For whatever reason it doesn't want to save. And its not a permissions settings as I have full rights.

Code is as follows, if anyone can help I'd be most greatful!

=============ASP====================================
Set xslDoc = Server.CreateObject("Msxml2.FreeThreadedDOMDocument.3.0")
xslDoc.async = False
xslDoc.setProperty "SelectionLanguage", "XPath"
xslDoc.load( Server.MapPath("styles/xsl/rep_service_action.xsl") )

Set xmlTemplate = Server.CreateObject("Msxml2.XSLTemplate.3.0")
xmlTemplate.stylesheet = xslDoc

Set myProc = xmlTemplate.createProcessor()
myProc.input = xmlGroupDoc

myProc.transform()

Set xmlNewDoc = Server.CreateObject("Msxml2.DOMDocument.3.0")
xmlNewDoc.async = False
xmlNewDoc.validateOnParse = False
xmlNewDoc.preserveWhiteSpace = True
xmlNewDoc.resolveExternals = False
xmlNewDoc = myProc.output
xmlNewDoc.save("C:\AMS_Final\MAINTENANCE\temp4.xml")
