embeding convertkit form: just showing actual code instead of form

I've been trying to embed my Convertkit form into Squarespace.  I do have a Squarespace business account and have followed the steps of embedding a form using both the javascript and HTML.  For some reason when I paste the code, neither is working.  It is not even showing the "script disabled."   It is just pasting the actual code into my code block.  

Does anyone know why this is happening?

Anyone have a solution or workaround that does not involve Zapier?

Appreciate any help!

Hi. It is default message in Edit Mode. You can check preview mode/open incognito to check to see if it works or not.
