URGENT!!! Coming Soon Page

I have a Mailchimp sign up form and a Soundcloud file I need to embed on my coming soon page. I’ve copied the code from MC and SC and ensured that they do work (on regular blog pages). But they are not working in Maintenance/Coming Soon mode – the editor isn’t interpreting the html (because you can only add content in Visual mode, there is no Text mode like in the regular text editor modules?) and all I’m getting is either nothing or the raw code showing on the page.

I’ve had the form embedded in an accordion (old version) and it worked, but now nothing I try is working.

I will upload an image of the code I’m using and how I’m inputting it. It hasn’t mattered if I put the embed code in a text box, accordion, content box, or raw.
