Hello @L74372 ,
If you're not able to get what you need to from installing the form on your Wordpress .org site, then you may not be able to utilize it. WP sites, both .org and .com tend to be very restrictive with outside scripting, meaning certain elements may not work with the coded forms, or in the case of .com sites just won't be compatible at all.
Generally speaking, I'd advise using either the WP integration, or a landing page form.
