Integrating a Custom Facebook Conversion after a Form Signup

Hey everyone,

we are currently experimenting with Webflow as the tool to create our landing pages with.
One first project is the creation of a custom Landing page for a webinar event.
Main feature is a form, where people land after clicking on a facebook ad. The form button has the ID:“submitButton”. We also added this code snippet to track our events:

<!-- Add Pixel Events to the button's click handler -->
<script type="text/javascript">
  var button = document.getElementById('submitButton');
    function() { 
      fbq('track', 'Lead', {
        value: 20,
        currency: 'USD' 

We’ve been using the “Test Events” function from the Facebook Pixel to assure our setup is working before launch, but unfortunately, it doesn’t.

Some more info:
We host landing pages on a subdomain of our website since the main one is hosted on WP.
Other events like “ViewContent” already get tracked on the Webflow Landing Page.

Thanks for your help in advance.
