Problems with gun shop cloning guns?

Greetings,

I've made a gun shop, and at first sight works well, but after buying a gun the script clones the last gun and puts both in the player backpack. How can I solve it?

Scripts: Buy button script

--[[
	Script made by: Time_URSS
	Gui buttons and shopping
--]]

--//Variables\\--
local player = game.Players.LocalPlayer
local button = script.Parent
local name = button:WaitForChild("FinalName")
local price = button:WaitForChild("FinalPrice")
local nameText = button.Parent.Name
local priceText = button.Parent.Price
local replicatedStorage = game:GetService("ReplicatedStorage")
local verificationTab = button.Parent.Parent.Parent.Verification

--//Functions\\--
local function buyProcess()
	local weapon = replicatedStorage:WaitForChild("Guns"):FindFirstChild(name.Value)
	if weapon then
		if player.leaderstats.Rubbles.Value >= price.Value then
			verificationTab.Visible = true
			verificationTab.Yes.MouseButton1Click:Connect(function()
				verificationTab.Visible = false
				player.leaderstats.Rubbles.Value = player.leaderstats.Rubbles.Value - price.Value
				local clonedWeapon = weapon:Clone()
				clonedWeapon.Parent = player.Backpack
				print("Gun successfully bought, transaction ended well.")
			end)
			verificationTab.No.MouseButton1Click:Connect(function()
				verificationTab.Visible = false
				warn("Gun failed to be bought, transaction cancelled.")
			end)
		else
			warn("Player does not have enough Rubbles to buy the gun. Wait until you've enough.")
		end
	else
		error("Weapon not found, please contact Time_URSS to fix the error. ERROR#050")
	end
end

button.MouseButton1Click:Connect(buyProcess)

Both buttons script

--[[
	Script made by: Time_URSS
	Gui buttons and shopping
--]]

--//Variables\\--
local player = game.Players.LocalPlayer
local button = script.Parent
local buybutton = button.Parent.Parent.Information.Buy
local priceText = button.Parent.Parent.Information:WaitForChild("Price")
local nameText = button.Parent.Parent.Information:WaitForChild("Name")

--//Values\\--
local name = button:WaitForChild("Name")
local description = button:WaitForChild("Description")
local characteristics = button:WaitForChild("Characteristics")
local price = button:WaitForChild("Price")

--//Functions\\--
local function onClicked()
	print("Attempted to buy the "..name.Value..".")
	priceText.Text = "Price: "..price.Value
	nameText.Text = "Name: "..name.Value
	buybutton:WaitForChild("FinalPrice").Value = price.Value
	buybutton:WaitForChild("FinalName").Value = name.Value
end

button.MouseButton1Click:Connect(onClicked)

I hope I get help
