My punch script spams FireServer() and only does 1 type of punch?

I made a punch script and for some odd reason, with no errors, the punch script only does a Left Punch, and it's spammable if I didn't put in the cooldown in the local script. Here's the server sided.

local PunchEvent = game.ReplicatedStorage.punch
local Cooldown = 0.4

local PunchData = {}

local function PlaySound(ID,Parent)
    local Sound = Instance.new("Sound")
    Sound.SoundId = "rbxassetid://"..ID
	Sound.PlayOnRemove = true
    Sound.Parent = Parent
    Sound:Destroy()
end

local torw = 711753382

PunchEvent.OnServerEvent:Connect(function(Player)
	local Character = Player.Character	
	
	while Character.Parent == nil do
		wait()
	end
	
	local Humanoid = Character:WaitForChild("Humanoid")
	local Animator = Humanoid:WaitForChild("Animator")
	
	PunchData[Player] = {
		["LeftPunch"] = Animator:LoadAnimation(script.Left),
		["RightPunch"] = Animator:LoadAnimation(script.Right),
		["LastPunch"] = "LeftPunch",
		["CanPunch"] = true
	}
	
	local SecondaryDataTable = PunchData[Player]
	
	local RightHand = Character.RightHand
	local LeftHand = Character.LeftHand

	local CurrentConnection = nil
	local CurrentAnimationTrack = nil
	
	if SecondaryDataTable.CanPunch then
		if SecondaryDataTable.LastPunch == "LeftPunch" then
			SecondaryDataTable.CanPunch = false
			PlaySound(711753382, Character.RightHand)
			CurrentAnimationTrack = SecondaryDataTable.RightPunch
			
			CurrentConnection = Character.RightHand.Touched:Connect(function(Hit)
				local Humanoid = Hit.Parent:FindFirstChildOfClass("Humanoid")
				if Humanoid then
				Humanoid:TakeDamage(12)
				PlaySound(367499850, RightHand)
				CurrentConnection:Disconnect()
				end
			end)
			
			SecondaryDataTable.LastPunch = "RightPunch"
			
		elseif SecondaryDataTable.LastPunch == "RightPunch" then
			SecondaryDataTable.CanPunch = false
			PlaySound(711753382, LeftHand)
			CurrentAnimationTrack = SecondaryDataTable.LeftPunch
			
			CurrentConnection = Character.LeftHand.Touched:Connect(function(Hit)
				local Humanoid = Hit.Parent:FindFirstChildOfClass("Humanoid")
				if Humanoid then
				Humanoid:TakeDamage(12)
				PlaySound(367499850, LeftHand)
				CurrentConnection:Disconnect()
				end
			end)
			
			SecondaryDataTable.LastPunch = "LeftPunch"
			
		end
		CurrentAnimationTrack:Play()
		CurrentAnimationTrack.Stopped:Wait()
		if CurrentConnection then CurrentConnection:Disconnect() end
		
		wait(Cooldown)
		SecondaryDataTable.CanPunch = true
	end
end)

And here's the local script.

local Player = game.Players.LocalPlayer
repeat wait() until Player.Character

local Mouse = Player:GetMouse()
local PunchEvent = game.ReplicatedStorage.punch

local TakeStamina = game.ReplicatedStorage.TakeStamina

local Data = Player.Data
local Stamina = Data.Stamina

local Debounce = false

Mouse.Button1Down:Connect(function()
	if Stamina.Value > 11 then
		if not Debounce then
		Debounce = true
		PunchEvent:FireServer()
		TakeStamina:FireServer(10)
		wait(0.4)
		Debounce = false
		end
	end
end)
