Video slide is not showing

Yes, that should work.

Could I see the website you’re trying it on? Perhaps something is causing an error.

It’s stil in sandbox mode, but here it is:

Thanks. It looks like you put the entire video URL in, rather than the video ID. The video ID is ‘FBIWazTwMaI’, which you should use in the video slide.

I tried with the hole URL because the ID didn’t work.
Now it works.
Thanks for your time.

I’m glad to hear that, you’re very welcome!
