Calling BSM Web Service...

I'm trying to return Annotations from a BSM scorecard by calling the PMService.asmx web service. I can successfully call operations like "GetScorecards" that require no parameters...but I keep getting the same error when trying to call "GetAllAnnotationsbyScorecardID"



Here is the Query:



<Query>
<SoapAction>http://www.microsoft.com/performancemanagement/scorecards/GetAllAnnotationsByScorecardID</SoapAction>
<Method Namespace="http://www.microsoft.com/performancemanagement/scorecards/" Name="GetAllAnnotationsByScorecardID">
<Parameters>
<Parameter Name="scorecardID">
<DefaultValue>7e3b541b-51db-4ded-b8f3-f7e8f6657c42</DefaultValue>
</Parameter>
</Parameters>
</Method>
</Query>





Here is the XML error returned:



<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlnsoap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soaperver</faultcode>
<faultstring>Server was unable to process request. --&gt; scorecardID</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>




Am I structuring the Query the right way? Not sure if I'm a passing the guid correctly...I got the scorecard guid from the result set of calling "GetScorecards"
