How do I fix this clone script?

wait(1)

local player = game.Players.LocalPlayer
local Mouse = player:GetMouse()
local humanoid = player.Character.Humanoid 
local s = humanoid:LoadAnimation(game.StarterPack.HandSign.Animation)


Mouse.KeyDown:connect(function(key)
game.Players.PlayerAdded:connect(function(player)
player.CharacterAdded:connect(function(character)
	local CharacterChildren = character:GetChildren() 
	for i,v in pairs(CharacterChildren) do
	local Clone = v:Clone()
	if key:lower() == "h" and humanoid then
    s:Play()
	player.Character.Humanoid.WalkSpeed = 16
	wait(.7)
	Clone.Parent = game.Workspace.Character 
	end
	end
end)

I'm tryna make the player play an animation, wait .7 seconds then a clone pops up right behind the player. But nothing is working. How do I fix this?
