Multiple Stands Error. Why?

Hello, so i wanted to start a Jojo Bizarre Adventure game and i have scripted so that whenever you press q a stand will come out and if you press q while you have it out it will go back but instead of that it is just coming more and more.Any help?

local Player = game:GetService("Players").LocalPlayer

local rp = game:GetService("ReplicatedStorage")
local summon = rp:WaitForChild("Summon")

local UIS = game:GetService("UserInputService")

local isActive = false
local debounce = false
local cd = 1

UIS.InputBegan:Connect(function(input,isTyping)
	if isTyping then
		return
	elseif input.KeyCode == Enum.KeyCode.Q then
		if debounce == false and isActive == false then
			isActive = true
			debounce = true
			
			summon:FireServer(isActive)
			wait(cd)
			debounce = false
		elseif debounce == false and isActive ==  true then 
			isActive = false
			debounce = true
			
			summon:FireServer(isActive)
			wait(cd)
			debounce = false
		end
	end
end)

and this:

local rp = game:GetService("ReplicatedStorage")
local summon = rp:WaitForChild("Summon")

local TweenService = game:GetService("TweenService")

summon.OnServerEvent:Connect(function(Player,isActive)
	local Character = Player.Character
	local Humanoid = Player:FindFirstChild("Humanoid")
	local Humrp = Character.HumanoidRootPart
	
	if isActive then
		local Stand = script:WaitForChild("Stand"):Clone()
		Stand.Parent =  Character
		Stand.PrimaryPart.CFrame = Humrp.CFrame
		
		local weld = Instance.new("ManualWeld")
		weld.Part0 = Stand.PrimaryPart
		weld.Part1 = Humrp
		weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
		weld.Parent = weld.Part0
		
		local AnimControl = Stand:FindFirstChild("AnimControl")
		
		local Idle = AnimControl:LoadAnimation(script.Idle)
		Idle:Play()
		
		local goal = {}
		goal.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
		goal.C1 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame * CFrame.new(-3,1,2))
		local info = TweenInfo.new(.5)
		local tween = TweenService:Create(weld,info,goal)
		tween:Play()
		
	else
		
	end
	
end)
