How do you pass IXMLDOMElement to a function or subroutine?

Code sample below

Dim objxml

Set objxml = Server.CreateObject("Microsoft.XMLDOM")

objxml.LoadXml(rsDef("ImportXml")&"")

Set BucketTypeNode=objxml.SelectSingleNode("//tblBucketType")

response.Write typeName(BucketTypeNode) ' Writes IXMLDOMElement

response.Write ConvertNodeToInsert(BucketTypeNode) '<--Errors Here Type mismatch: 'ConvertNodeToInsert'

Thanks!
