Animation script Isnt working

I have a custom character model and rig and I made this script to have an animation play all the time but the animation doesn’t seem to work.


I have tried using AnimationTrack and loading the animation there I have tried Humanoid and loading the animation there doesn’t seem to work either.

local humanoid = script.Parent.Humanoid

local animation ="Animation")
animation.AnimationId = ""
local animationTrack = humanoid:LoadAnimation(animation)
