Why my block animation doesn't work? It my UIS that is wrong?

local Player = game.Players.LocalPlayer
local Character = Player.Character

UIS = game:GetService("UserInputService")

local Block = script.Block

UIS.InputBegan:Connect(function(input, gameProccesedEvent)
	local Humanoid = script.Parent:FindFirstChild("Humanoid")
	local Block = script.Bloqueo 							---is an animation---
	if input.KeyCode == Enum.KeyCode.R then
		local BlockTrack = Humanoid:LoadAnimation(Block)
		BlockTrack:Play()
	end
end)
