Why dosen't this humanoid load animation work?

local Humanoid = script.Parent

Animation = script:WaitForChild("Animation")

local LoadedAnimation = Humanoid:LoadAnimation(Animation)

LoadedAnimation:Play()

Basically I want to use it to preview animations for a shop, I got the viewport setup but the animation doesn't play.

I tested on my studio and it worked perfectly, I don't know what's wrong with yours but the only thing that I might be able to help with is instead of having the script inside the humanoid, have it in the model, this is the code that I used

local Humanoid = script.Parent:WaitForChild('Humanoid')

local Animation = script:WaitForChild("Animation")

local LoadedAnimation = Humanoid:LoadAnimation(Animation)

LoadedAnimation:Play()

hope this helps! if it works plz accept my answer lol Also, if you are using a localscript, make sure that it is not in the workspace. This means if the parent of the model is workspace

Make a local script located in StarterCharacterScripts. I've tried putting it in StarterPlayerScripts, but for some reason the local character is nil in the script when I put it there. Also make sure the animation is a child of the script, so when the animation goes to the character the animation stays with it.
