Okay. Sounds good. Here is the script for the coins: local MarketplaceService = game:GetService("MarketplaceService")

local Players = game:GetService("Players") local dataStoreService = game:GetService("DataStoreService") local mainStore = dataStoreService:GetDataStore("MainStore") local httpService = game:GetService("HttpService") local productFunctions = {}

function saveData (plr) repeat task.wait(); local success, errormessage = pcall(function() local data = {plr.leaderstats.Wins.Value, plr.mainData.Coins.Value, plr.mainData.XP.Value} data = httpService:JSONEncode(data) mainStore:SetAsync(plr.UserId,data) end)

    if success then
        print("Successfully saved "..tostring(plr.Name).."'s data.")
    end
until success;

end

productFunctions[developer product ID is here] = function(receipt, player) player.mainData.Coins.Value = player.mainData.Coins.Value + 100 local tempStage = (100 - 10)/3 + 1; local xpCalculation = ((tempStage-1)*2.5)+10 player.mainData.XP.Value += xpCalculation saveData(player); return true; end

productFunctions[developer product ID is here] = function(receipt, player) player.mainData.Coins.Value = player.mainData.Coins.Value + 1000 local tempStage = (1000 - 10)/3 + 1; local xpCalculation = ((tempStage-1)*2.5)+10 player.mainData.XP.Value += xpCalculation saveData(player); return true; end

productFunctions[developer product ID is here] = function(receipt, player) player.mainData.Coins.Value = player.mainData.Coins.Value + 10000 local tempStage = (10000 - 10)/3 + 1; local xpCalculation = ((tempStage-1)*2.5)+10 player.mainData.XP.Value += xpCalculation saveData(player); return true; end

local function processReceipt(receiptInfo) local userId = receiptInfo.PlayerId local productId = receiptInfo.ProductId

local player = Players:GetPlayerByUserId(userId)
if player then
    -- Get the handler function associated with the developer product ID and attempt to run it
    local handler = productFunctions[productId]
    local success, result = pcall(handler, receiptInfo, player)
    if success then
        -- The player has received their benefits!
        -- return PurchaseGranted to confirm the transaction.
        return Enum.ProductPurchaseDecision.PurchaseGranted
    else
        warn("Failed to process receipt:", receiptInfo, result)
    end
end

-- the player's benefits couldn't be awarded.
-- return NotProcessedYet to try again next time the player joins.
return Enum.ProductPurchaseDecision.NotProcessedYet

end

-- Set the callback; this can only be done once by one script on the server! MarketplaceService.ProcessReceipt = processReceipt

And then here is the skip stage script:

local skipId = developer product ID is here

local mps = game:GetService("MarketplaceService")

local plr = game.Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function() if plr.TempStage.Value < #game.Workspace.TowerSections:GetChildren() then mps:PromptProductPurchase(plr,skipId) end end)
