Animations are inconsistent, can I get some help?

The animations are supposed to play 4 secs apart from each mouse click but take from between 20 - 3 seconds to do. I have no idea how to fix this. Not to mention the audio does not play when damage is done.

(Note: The animations are in R6) The tutorial I am watching to do this: http://https://www.youtube.com/watch?v=vh8Ggpp_RR4

Enabled = true

script.Parent.OnServerEvent:Connect(function(Player, Action, V1)
    local c = Player.Character
    if Enabled == false then return end
	    if Action == "AS" then
		Enabled = false
        local Punch = Instance.new("Animation")
        Punch.AnimationId = "rbxassetid://5236034047"
        local Anim = c.Humanoid:LoadAnimation(Punch)
		Anim:Play()
		end
		 wait(4)
        	local Region = Region3.new(V1-Vector3.new(2,2,2),V1+Vector3.new(2,2,2))
        	local RTable = workspace:FindPartsInRegion3(Region,nil,2)
        	for i,v in pairs(RTable) do
        	if v.Parent:FindFirstChild("Humanoid")and v.Parent:FindFirstChild("Deb") == nil and v.parent ~=c then
        	local Deb = Instance.new("BoolValue",v.Parent)
        	Deb.Name = "Deb"
        	game.Debris:AddItem(Deb,0.2)
			v.Parent.Humanoid:TakeDamage(20)
			local s = Instance.new("Sound")
			s.SoundId = "rbxassetid://444667824"
			s.PlaybackSpeed = math.random(80,120)/100
			s:Play()
		    end
		wait(4)
        Enabled = true
    end
end)
