Does Anybody Know Why This Script Isn't Working?
This script is supposed to add whoever bought the developers product add "Money" to the leaderboard. I got this script from the roblox wiki and edited it a little
--LocalScript in StarterPack -- setup local variables local buyButton = game.StarterGui.Donations.DonationAmounts.Donate50Tx local productId = 20806015
-- when player clicks on buy brick prompt him/her to buy a product buyButton.MouseButton1Click:connect(function() game:GetService("MarketplaceService"):PromptProductPurchase(game.Players.LocalPlayer, productId) end)
--Script in BuyButton part -- setup local variables local MarketplaceService = Game:GetService("MarketplaceService") local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory") local productId = 20806015
-- define function that will be called when purchase finished MarketplaceService.ProcessReceipt = function(receiptInfo)
-- find the player based on the PlayerId in receiptInfo
for i, player in ipairs(game.Players:GetChildren()) do
if player.userId == receiptInfo.PlayerId then
-- check which product was purchased
if receiptInfo.ProductId == productId then
-- handle purchase
player.leaderstats.Money.Value = player.leaderstats.Money.Value + 50
end
end
end
-- record the transaction in a Data Store
local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.PurchaseId
ds:IncrementAsync(playerProductKey, 1)
-- tell ROBLOX that we have successfully handled the transaction
return Enum.ProductPurchaseDecision.PurchaseGranted
end

Hello. I currently take this as you wish to ProcessReceipt(). You also stated that you got this from the Wiki article. So I will base my answer off of that.
I have a game that uses the same script that is on the wiki, so my suggestion is, leave it as unedited as possible.
local MarketplaceService = game:GetService("MarketplaceService")
local HealthID, GoldID = 11111, 22222
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
MarketplaceService.ProcessReceipt = function(receiptInfo)
local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
if PurchaseHistory:GetAsync(playerProductKey) then
return Enum.ProductPurchaseDecision.PurchaseGranted --We already granted it.
end
-- find the player based on the PlayerId in receiptInfo
for i, player in ipairs(game.Players:GetPlayers()) do
if player.userId == receiptInfo.PlayerId then
-- check which product was purchased (required, otherwise you'll award the wrong items if you're using more than one developer product)
if receiptInfo.ProductId == HealthID then
-- handle purchase. In this case we are healing the player.
player.Character.Humanoid.Health = 100
elseif receiptInfo.ProductId == GoldID then
-- handle purchase. In this instance we're giving the player 100 extra gold.
player.leaderstats.Gold.Value = player.leaderstats.Gold.Value + 100
end
end
end
-- record the transaction in a Data Store
PurchaseHistory:SetAsync(playerProductKey, true)
-- tell ROBLOX that we have successfully handled the transaction (required)
return Enum.ProductPurchaseDecision.PurchaseGranted
end
Let's break this code down piece by piece for a better understanding of what each piece means.
local MarketplaceService = game:GetService("MarketplaceService") Is as simple as can be, it requests the MarketplaceService, which is required for anything using R$ or TIX.
local HealthID, GoldID = 11111, 22222 This is what is very easy once you learn it (if you don't already know what it means). The "HealthID" is 11111 and the "GoldID" is 22222 so if you wish to set this up for your own items you should set the line up as:
local item1,item2,item3 = 11111, 22222, 33333 the numbers should be replaced by your Developer Product IDs. The item names can be changed to whatever, just do not name two things the same.
The rest is really just Lua jibberish and unneeded for your question. So we will go down to the next part that matters.
if receiptInfo.ProductId == HealthID then If we use my example from above, this would say if receiptInfo.ProductId == item1 then the line under that would give something such as extra health, or faster walkspeed. But instead of doing end we will do something else... elseif So, our next product should be elseif receiptInfo.ProductId == item2 then then give them another powerup or whatever you wish for them to have. If you wish to have more, continue doing elseif for your next item(s).
Please note: You do not have to use this for multiple purchases if you do not have multiple products. You just don't have to put any elseif or anymore local items. Please be sure to use this one script for any and all developer products. This script will prevent you from having a bunch of the same scripts clogging up your ServerScriptService (which is by the way where this is supposed to go) and it helps you find the needed product quicker.
I hope this helped you!
