The Animation is not Playing when I am Equipping a Gun?

I tried making an UserInputService, when player presses Q, the animation plays, and it worked fine.

But when I try to make the same but when the tool is clicked it doesn't work. I don't get any error or anything, it just won't play, am I missing something?!

local Mouse = game.Players.LocalPlayer:GetMouse()

script.Parent.Activated:Connect(function()
if Mouse.Target then
		if Mouse.Target.Parent:FindFirstChild("Humanoid") then
			print("There is humanoid")
			script.Parent.RemoteEvent:FireServer(Mouse.Target)
			game.Players.LocalPlayer.Character.Humanoid.Animator:LoadAnimation(game.ReplicatedStorage.Animation):Play()
		else
			print("No Humanoid")
		end
	end
end)

Well It Might Not Be A Problem In Your Script, But Did You Add The Animation?

That's because Mouse.Target has built-in filter for all Characters. You can only do this using Raycasting.
