Please put this code to be directed after my Submit button

<script>
fbq('track', 'CompleteRegistration');
</script>

Please take note that you cannot insert Javascript code into the Form Builder. It will be stripped automatically upon saving the form or when you preview it.

If you want, you can download the full source code so that you can customize the HTML, CSS and Javascript files of the form. Here's a guide: How-to-get-the-Full-Source-Code-of-your-Form.

Hope that helps. Thank you.

The "Thank You" after my Submit button doesn't work.  Nor does the auto responder
