Type mismatch error in soapmapper

What could be causing the error

Soapmapper: converting data for soapmapper failed inside the typemapper
HRESULT=0x80020005: type mismatch

when running the code below?

's is a valid XML 
xml_doc.LoadXML s

Dim Nds As MSXML2.IXMLDOMNodeList
Set Nds = xml_doc.ChildNodes

Dim module As clsws_ProfileManagement
Set module = New clsws_ProfileManagement

Set Value = module.wsm_MyProcedure(Nds)

Module is a reserved word in VBA. Try changing this in your code and see if it works.
