Why does my sliding announcement bar keep disappearing?

[DAGNORAK]

 

 

Greetings all, I’ve finally found a way to code a rolling announcement bar but now I have the issue that it keeps disappearing!!  (Dawn)
When I edit my store I can see it in sections, then I tick “show” and fill in the messages and once I hit save it disappears and doesn’t show. Can anyone point me to the issue ? Thanks I’ll attach all info
