Error with embed code for "Creating Playlist"

Hi,

I can't get the "Creating Playlist" video to work on my site.

I have been working with other videos and they have been working fine. This one just wouldn't work.

Help?

The code is "<iframe src="https://premium.wpmudev.org/video/playlists” frameborder="0" width="500" height="281" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>".

I've tried removing the special characters, "”", but it made no difference.

I've currently set this post as a private post, so you would not be able to see it on my site.

Would appreciate it if you could send me an embed code that would work for this video.

Regards,
Elina
