在Excel xp中通过xml/soap提交表单

[mot]

在Excel xp中通过xml/soap提交表单给web service.以下是VBA代码

Dim Client As SoapClient
Dim sRvalue As Boolean
' Create and initialize a SOAP client object.
Set Client = New SoapClient

' Take the value from cell 104, this is where the SOAP init
' value is stored.
Client.mssoapinit wsdlURL
...
' Submit the XML spreadsheet and GUID value to sendmsg.
' The SOAP server will pass these values to the BizTalk Server.
sRvalue = _
Client.sendmsg(ActiveSheet.Range("a1:o104"). _//出错行
Value(xlRangeValueXMLSpreadsheet), Guid)

出错行提示运行是错误：无效的过程调用或参数。
请问大虾是什末原因
