Linkedin autofill

Hi,

I want to add a inkedin autofill button to a form (created with contact form 7) like this : https://business.linkedin.com/marketing-solutions/cx/17/02/the-sophisticated-marketers-guide-to-linkedin

I followed the installation procedure step by step : https://www.linkedin.com/help/lms/answer/65688/linkedin-autofill-setup-guide?lang=en
This instructions didn’t work for me.

In the file functions.php in my theme’s child, I’ve added this :

function linkedin_autofill(){
?>
<script src=”https://www.linkedin.com/autofill/js/autofill.js&#8221; type=”text/javascript” async></script><script type=”IN/Form2″ data-form=”212″ data-field-firstname=”your-firstname” data-field-lastname=”your-name” data-field-phone=”your-tel” data-field-email=”your-email”></script>
<?php
}
add_action(‘wp_footer’, ‘linkedin_autofill’);

Anyone has try to install this ? Anyone can help me ?
Thanks in advance

Regards

Xaav
