Try Studio

Hi,

You can try this template in your custom module.

<template id="portal_template_inherited_1"  inherit_id="portal.portal_my_details_fields">
<xpath expr="//input[@name='company_name']" position="replace"/>
<xpath expr="//label[@for='company_name']" position="replace"/>
    <xpath expr="//label[@for='vat']" position="replace"/>
    <xpath expr="//input[@name='vat']" position="replace"/>
</template>

Hope it helps
