reading value from jdbc query in a Script Assertion

I am trying to use the jdbc test step to read a value from the database and assign it to as a property in the context. The sql runs and I see valid data in the XML panel

<Results>
    <ResultSet fetchSize="0">
        <Row rowNumber="1">
            <VERIFYCONTACT.NONCE>Fv5IjrEVWtqR5me20cOUgx+W072QOWCq</VERIFYCONTACT.NONCE>
        </Row>
    </ResultSet>
</Results>

But when I execute the Script Assertion no value is found for the xpath location

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def holder = groovyUtils.getXmlHolder( "Response" )
def nonce = holder["//VERIFYCONTACT.NONCE"]
log.info(nonce.length)
assert nonce

Is "Reponse" the correct string I should supply to get the Response for the current Test Step?
