docusign template custom field not being filled

I am trying to get the custom fields that I have added to my template to be filled with the values I am sending in the xml request document. I am positive it is an obvious mistake, but I am just not seeing it. I also see this question askd a couple other times without an answer. this is my request. I can sign the document, but non of the non standard fields are filled.

<envelopeDefinition xmlns="http://www.docusign.com/restapi">
    <status>sent</status>
    <emailSubject>Disclosuresave - Clue Authorization Form</emailSubject>
    <templateId>x</templateId>
    <templateRoles>
        <templateRole>
            <email>test@test.test</email>
            <name>test name</name>
            <roleName>Recipient</roleName>
            <clientUserId>####</clientUserId>
            <CustomFields>
                <CustomField>
                    <Name>Address</Name>
                    <Show>True</Show>
                    <Required>False</Required>
                    <Value>123 Ash St</Value>
                </CustomField>
                <CustomField>
                    <Name>City</Name>
                    <Show>True</Show>
                    <Required>False</Required>
                    <Value>Beverly Hills</Value>
                </CustomField>
            </CustomFields>
        </templateRole>
    </templateRoles>
</envelopeDefinition>

If the fields that you're trying to fill are data fields that you've placed on the documents within the Template, then these aren't "custom fields" -- they're "tabs". If that's your scenario, then the tabs portion of your request should look like this:

<tabs>
    <textTabs>
        <text>
            <name>Address</name>
            <value>123 Ash St</value>
        </text>
        <text>
            <name>City</name>
            <value>Beverly Hills</value>
        </text>
    </textTabs>
</tabs>

Also, do note that element names are case-sensitive (i.e., "name" not "Name", "value" not "Value", etc.) -- AND, the value of the name element for each tab is case-sensitive as well. For example, if the Template defines the tab label as City but your API request sets name = city, then the API request won't populate that field in the Envelope (because City != city).
