Add script code to footer

Hi Enfold-team

I looked through other threads like https://kriesi.at/support/topic/integrate-java-script-code-into-the-footer-before-the-end-tag/ , your documentation and a lot of info on other sites, but I don’t find a solution.

As in the thread mentioned above, I’d like to add Amazon tracking code to the footer. I tried adding it to my child theme functions.php.

But no matter what I insert, it’ll crash the site and give the error “Parse error: syntax error, unexpected ‘}’, expecting end of file in /www/htdocs/w011980a/wp-content/themes/enfold-child/functions.php on line 5” or similar ones.

I entered this code according to your documentation:

function add_amazon_associates_code_in_footer(){
?>
<script src=”//z-na.amazon-adsystem.com/widgets/onejs?MarketPlace=US&adInstanceId=6938ec11-aacc-472c-XXXX-XXXXXXXXXXXXX”></script>
<?php
}
add_action(‘wp_footer’, ‘add_amazon_associates_code_in_footer’);

Alternatively, I could add this asynchrous code which is recommended:

<div id=”amzn-assoc-ad-6938ec11-aacc-472c-a644-XXXXXXXXX”></div><script async src=”//z-na.amazon-adsystem.com/widgets/onejs?MarketPlace=US&adInstanceId=6938ec11-aacc-472c-a644-XXXXXXXXXXX”></script>

I’d appreciate your help on this.
Thank you in advance
