Why does my animation that I made wont work?

So I made a "dab" animation (Yeah I did..;p) and it works. I made a dancing animation but it wont work. Can somebody help me? The dance animation is the same as the dab animation, (the scripts) just diff animation ID.

local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/Asset?ID=1630032947"
local trackanimation = nil
local playability = true
function playAnimation(AnimationSource)
if playability == true then
 local plr = game.Players.LocalPlayer
 trackanimation = plr.Character.Humanoid:LoadAnimation(animation)

 trackanimation.KeyframeReached:connect(function(kf)
print('working')
end)
trackanimation:Play()
end
end
script.Parent.MouseButton1Click:connect(playAnimation)
