Why has my submission button disappeared?

I have embedded the code onto an unbounce page but its not transferred over?

<script type="text/javascript" src="https://form.jotformeu.com/jsform/62762801188359"></script>

It seems, the form conflicts with the existing script on your page that's why it was not working as expected. Re-embedding your form using iframe embed code should fix it since the form loads in an iframe container, therefore it won't conflict with anything on your page.

If you have any query, or need further assistance, feel free to revert back.

Thanks.
