Embedder Not working

When using the Dropbox Embedder, there are two ways to run it, as covered in that documentation under the two sections:

1. "Embedding Files or Folders using anchor tags"
2. "Triggering the Embedder using JavaScript"

For both of those though, you need to load the "dropins.js" script, e.g., via the <script> tag that you showed.

So, it sounds like method 1 is working for you, but method 2 isn't? Is that correct?

In any case, we'll need some more information to help troubleshoot this. Can you share the rest of the relevant code you're using, as well as any error or output you're getting when this fails? E.g., check the JavaScript console.
