Trying to add an in-line subscibe form


I’m trying to add an inline form to a page on my blog, using Flodesk’s instructions*.

As such:

  1. I’ve tried adding the given Inline Code* to my ‘custom javascript’ section
  1. And then tried adding the given Header Code* to a post (using the plain editor)

Alas, no luck.

Please can someone help? I have a feeling I need to add a header tag in #1

Thank you!
