Accept.js Recurring Payment getting customer name

1MSC2020 — Mon, 25 Jan 2021 20:46:55 GMT

I have gotten Accept.js hosted form to create a subscription. The problem is it wants the customer's name. I just have the hardcoded names from the example to get it to work. The customer name is in the hosted form but I do not see how it is passed to the XML file. Does anyone know how to pass the name?

 <?xml version="1.0" encoding="UTF-8"?>
        <ARBCreateSubscriptionRequest>
            <merchantAuthentication></merchantAuthentication>
            <subscription>
                <name>Sample subscription</name>
                <paymentSchedule>
                    <interval>
                        <length>1</length>
                        <unit>months</unit>
                    </interval>
                    <startDate>2021-04-30</startDate>
                    <totalOccurrences>12</totalOccurrences>
                    <trialOccurrences>1</trialOccurrences>
                </paymentSchedule>
                <amount>10.29</amount>
                <trialAmount>1.00</trialAmount>
                <payment>
                    <opaqueData>
                    <dataDescriptor>assignDD</dataDescriptor>
                    <dataValue>assignDV</dataValue>
                    </opaqueData>
                </payment>
                <billTo>
                <firstName>John</firstName>
                <lastName>Smith</lastName>
                </billTo>
            </subscription>
        </ARBCreateSubscriptionRequest>
        XML;
