Assignment Fault - No results for expression

[Alex Boisvert]

I don't know if it's a copy & paste issue but I see a discrepancy between:

<ns:properties>
    <ns:propertyName>deviceID</ns:propertyName>
    <ns:propertyValue></ns:propertyValue>
</ns:properties>

and your XPath expression:
bs:Properties[bs:PropertyName='deviceID']/bs:PropertyValue

The case of the element names don't match.
