Why does this work on studio and not on server?

this is something where you press r and it playes a anamation and the anamation plays on studio but not on server this is in workspace and its a script here is code

wait(2)
local Damage = 1
me = game.Players.LocalPlayer
Playa = game.Players.LocalPlayer
mouse = me:GetMouse()
Torso = me.Character.Torso
Head = me.Character.Head
Humanoid = me.Character.Humanoid
Neck = Torso["Neck"]
RightShoulder = Torso["Right Shoulder"]
LeftShoulder = Torso["Left Shoulder"]
RightHip = Torso["Right Hip"]
LeftHip = Torso["Left Hip"]
LeftArm = me.Character["Left Arm"]
RightArm = me.Character["Right Arm"]
LeftLeg = me.Character["Left Leg"]
RightLeg = me.Character["Right Leg"]
req = 50


-- Damage
function Damage1(hit)
if hit.Parent:findFirstChild("Humanoid") and hit.Parent.Name ~= me.Name then
hit.Parent.Humanoid:TakeDamage(3)
wait(.2)
end
end


---- C MOVE--
PlayzUf = Playa.Name 
CMoveCD = true
mouse.KeyDown:connect(function(Key)
if Key == "r" and CMoveCD == true  and Humanoid.Jump == false then
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/item.aspx?id=321445347"
local animTrack = Humanoid:LoadAnimation(animation)
local Damage = 1
animTrack:Play()
wait(2)
local Damage = 0
end
end)
if Damage == 1 then
    Damage1(me.Character)
end
