Why doesn't my simple animation play??

I made a Hands Animation on a model made of bones, exported it and put set it to run in a localscript. But it doesn't play for some reason, it even prints "Shot Played" correctly. Pls Help

RS = game:GetService("RunService")

local plr = game.Players.LocalPlayer
local cam = workspace.CurrentCamera
local mouse = plr:GetMouse()

local Hands = script.Parent.Hands
Hands.Parent=plr.Character

Shot = Hands.AnimationController:LoadAnimation(script.Parent.Data.Shot)

mouse.Button1Down:Connect(function()
	Shot:Play() print("Shot Played")
end)

while true do
	RS.RenderStepped:Wait()
	Hands.armmesh.CFrame = cam.CFrame*CFrame.new(0,-1,-2)
end

Hello, is this script a local script and where did you put it?
