oRMControl = CreateObject("MwsProcessObj.RMController") oRMControl.set_up_environment(cXML) oRMControl.marshalldata(GetUserRS,"oUser") lnUsrKey = oRMControl.save( cXMLValidation )I tried setting cXMLValidation = "" before the call and that is where it errored out. The documentation states the cXMLValidation should be passed by reference so I tried @cXMLValidation and the Save does not error out, the save does not perform, lnUsrKey returns -3, but cXMLValidation does not contain anything but .NULL.
