How do I play a animation when I press a a certain key?

I tried to make a animation play by pressing Q. Nothing happened. Can you guys help me out?

local UserInputService = game:GetService("UserInputService") local localPlayer = game.Players.LocalPlayer

local animation = Instance.new("Animation") animation.AnimationId = "http://www.roblox.com/Asset?ID=492283384"

local animTrack = nil
local canPlay = true

local function onInputBegan(input, gameProcessed)
    if input.UserInputType == Enum.UserInputType.Keyboard then
        local keyPressed = input.KeyCode
        if keyPressed == Enum.KeyCode.Q then
	local player = game.Players.LocalPlayer.Character
		canPlay = false
		animTrack = player.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid
		animTrack.KeyframeReached:connect(function(keyframeName) -- Bind function to KeyframeReached event
			if keyframeName == "ElectrocuteEnd" then
				canPlay = true
end

end
          
    end
end
 
local function onInputEnded(input, gameProcessed)
    if input.UserInputType == Enum.UserInputType.Keyboard then
        local keyPressed = input.KeyCode
        if keyPressed == Enum.KeyCode.Q then
     local player = game.Players.LocalPlayer.Character
		canPlay = false
		animTrack = player.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid
		animTrack.KeyframeReached:connect(function(keyframeName) -- Bind function to KeyframeReached event
			if keyframeName == "ElectrocuteEnd" then
				canPlay = false
		end
    end
end
 
UserInputService.InputBegan:connect(onInputBegan)
UserInputService.InputEnded:connect(onInputEnded)
