I'm creating a mailchimp form in CMS page but this line of code is removed once I saved it. That's why once I send a form, no validation to a user if their request was sent or not.

```
<div class="response" id="mce-error-response" style="display:none"></div>
<div class="response" id="mce-success-response" style="display:none"></div>

```

How can I make it stay? 

Thanks!
