If person buys item then intvalue goes from 0 to 1. If value = 1 then it prints("BYU") How fix?

So I made a shop Gui and whenever you buy an item it changes the text from "Buy!" to purchased. I made the script so that when ever you buy an item it changes the IntValue called Purchase to 1(Meaning they bought it).

local price = script.Parent.Parent.Price
local tools = game.ReplicatedStorage:WaitForChild("Tools")
local tool = tools:FindFirstChild(script.Parent.Parent.ItemNameValue.Value)

local player =  game.Players.LocalPlayer
local cash = player.leaderstats:WaitForChild("Cash")
local Purchased1 = script.Parent.Parent.Parent.Frame.Item1.Purchased
local Purchased2 = script.Parent.Parent.Parent.Frame.Item2.Purchased
local Purchased3 = script.Parent.Parent.Parent.Frame.Item3.Purchased

if script.Parent.Parent.Purchased.Value == 0 then
	print("=0")
	if script.Parent.Parent.Purchased.Value == 1 then
		print("script")
	end
end
script.Parent.MouseButton1Click:Connect(function()
		if cash.Value >= price.Value then
		cash.Value = cash.Value - price.Value
		end
		if price.Value == 100 then
			local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
			oldGun:Destroy()
			game.ReplicatedStorage.Tools.Pistol:Clone().Parent = player.Backpack
			Purchased1.Value = 1
		end
				if price.Value == 300 then
			local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
			oldGun:Destroy()
			game.ReplicatedStorage.Tools.Revolver:Clone().Parent = player.Backpack
			Purchased2.Value = 1
				end
				if price.Value == 500 then
			local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
			oldGun:Destroy()
			game.ReplicatedStorage.Tools.Uzi:Clone().Parent = player.Backpack
			Purchased3.Value = 1
		end
end)

My problem is that when the intvalue == 1 it doesnt print("BYU")

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        if game.MarketplaceService:PlayerOwnsAsset(player,ID) then --The id is the id of the gamepass your selling
            SCIPRT HERE -- what you want executed when the player owns the gamepass
        end
    end)
end)
