Hi, Developers!

I’ve searched everywhere in devforum and google and how do I make a Value buy?

I made a whole GUI for this. When a player buys the coin product (dev product) they get the coins

Code for the leaderboard value.

local DataStoreService = game:GetService("DataStoreService") --Calls DataStoreService



local SavedData = DataStoreService:GetDataStore("SavedData") --Gets saved data
-----------------------------------------------------------------------------------------------------------------------
game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = player
	leaderstats.Name = "leaderstats"
	local coins = Instance.new("IntValue")
	coins.Name = "Coins"
	coins.Parent = leaderstats    


	local success,Data = pcall(function()
		return SavedData:GetAsync(player.UserId)
	end)
	if not Data then
		--Data = coins.Value == $0 useless junk =]
	end
	coins.Value = Data        
end)

game.Players.PlayerRemoving:Connect(function(player)
	local coins = player.leaderstats.Coins
	SavedData:SetAsync(player.UserId, coins.Value)
end)

Dev product buy code:

local productId = 1646286791 
local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:connect(function() 
	game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
end)

That’s all!

do you mean to say that you want to know how to know if a player bought the dev product or not?

#3

When someone buy a dev product, they get coins because they bought coins

#4

then just check if they bought the dev product and add the coins?

#5 
script.Parent.MouseButton1Click:connect(function() 
	game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
	player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 2000
end)

if you click it just give you coins, I’m trying to make when someone buys the product they get the coins.
