embed constant contact newsletter archive results in scripts disabled

I am trying to embed an archive of our constant contact emails on our site. When I paste the code as HTML or as an embed block it says, scripts disabled. I've tried everything from logging out, viewing in a private browser, disabling ajax, etc. I am frustrated that this capability is available on other site builder platforms but does not work on squarespace. 

Here is the code:

<!--Begin CTCT Archive-->

<script id="archiveScript" src="//static.ctctcdn.com/js/archive-static/current/archive-static.min.js"></script><div id="archiveList" data-archive-count="6" data-m="a07e2xp05b40"></div>

<!--End CTCT Archive-->

Two questions; do you have the business plan on Squarespace? Is the form enabled on Constant Contact?
