Animation won't play - lua

Question

I've made a GUI that has a WorldModel and when a player joins their character shows up on that GUI. All this works well but when I try to add an idle animation to it, it just won't run. I've tried different ways, loading the animation with animator, humanoid, but it just doesn't work. No errors.
Server Script (Creating animator):
local play = game.StarterGui:WaitForChild("Menu").Play
local uis = game:GetService("UserInputService")
local remote = game:GetService("ReplicatedStorage"):WaitForChild("Events").AnimPlay
game.Players.PlayerAdded:Connect(function(player)
local gui = player.PlayerGui:WaitForChild("CharacterShow")
local viewportframe = gui:WaitForChild("ViewportFrame")
local ClonedChar = game.Players:CreateHumanoidModelFromUserId(player.UserId)
ClonedChar.Parent = game:GetService("ReplicatedStorage")
local animator = Instance.new("Animator")
animator.Parent = ClonedChar.Humanoid
remote:FireClient(player,ClonedChar)
play.MouseButton1Click:Connect(function()
gui:Destroy()
end)
end)
Local Script (Creating animation, animationtrack, playing it, also making the GUI work, it has a turning feature too):
local player = game.Players.LocalPlayer
local remote = game:GetService("ReplicatedStorage"):WaitForChild("Events").AnimPlay
local uis = game:GetService("UserInputService")
local currentX
local MouseInDisplay, HoldInDisplay = false, false
local play = player.PlayerGui:WaitForChild("Menu").Play
local gui = player.PlayerGui:WaitForChild("CharacterShow")
remote.OnClientEvent:Connect(function(ClonedChar)
print("received")
local viewportframe = gui:WaitForChild("ViewportFrame")
local VPFcam = Instance.new("Camera")
VPFcam.Parent = viewportframe
VPFcam.CFrame = CFrame.new(0,0,0)
viewportframe.CurrentCamera = VPFcam
ClonedChar.Parent = viewportframe.WorldModel
ClonedChar.Name = "Character"
ClonedChar.Humanoid.DisplayDistanceType = Enum.HumanoidDisplayDistanceType.None
ClonedChar:SetPrimaryPartCFrame(CFrame.new(Vector3.new(0,0,-9.5),Vector3.new(0,0,0)))
local animator = ClonedChar.Humanoid.Animator
local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://11282795546"
local animtrack = animator:LoadAnimation(animation)
animtrack.Looped = true
animtrack.Priority = Enum.AnimationPriority.Action
animtrack:Play()
uis.InputBegan:Connect(function(input)
if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
if MouseInDisplay == true then
HoldInDisplay = true
currentX = nil
end
end
end)
uis.InputEnded:Connect(function(input)
if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
HoldInDisplay = false
end
end)
viewportframe.MouseMoved:Connect(function(X,Y)
if HoldInDisplay == false then return end
if currentX then ClonedChar.PrimaryPart.CFrame *= CFrame.fromEulerAnglesXYZ(0,((X-currentX)*.025),0) end
currentX = X
end)
viewportframe.MouseEnter:Connect(function() MouseInDisplay = true end)
viewportframe.MouseLeave:Connect(function() MouseInDisplay = false end)
end)
The animation ID is valid, and the game's owner created it.
