Creating a completed form success link to track conversions

Please tell me what is wrong in my code. The completed form does not land the user on another page, a thank you page I want to use to track conversions.

<script async type="text/javascript" src="https://static.klaviyo.com/onsite/js/klaviyo.js?company_id=XhP43x"><script type="text/javascript"> type="text/javascript">
 KlaviyoSubscribe.attachToForms('#email_signup', {
   hide_form_on_success: true,
   success_url: "https://sites.google.com/view/wudi-shilajit-gummies/accueil/thank-you"
 });
</script>
