Please post your Edge Project file for others to cross-check?
Also Muse embeds Edge Animate as an iframe within the Muse html file, so that particular interaction my not be the best use case.
Also Muse (the latest version) has some wonderful Parallax capbilities built in - here are a bunch of references to check out.
I used this coding and it is working with Edge animate but not with muse. I know that muse has wonderful parallax capabilities but it has some limitations. E.g. Scrolling won't stop after certain position and we can't set it to pinned to bottom or top.
