My Mechs animations are working but my zombies aren't?

The tutorial I've been watching gave people a little pack for some characters and all of there animations are ready but for 2 characters there animations had to be published 1 was the zombie I didn't want the other one, I will put his exact words "publish the animation yourself because this is just my animation" so he then said how to do it and then said this "and then get the id for yourself" so I got the id but I dont know if I should take the animation from my animations or use the id to get the animation like that. Can someone tell me how to do this.

you will have to take the ID from your animations. roblox doesnt allow other users to use other user's animations.
