How can i get this to work?

I have this Perk Shop script:

local MarketplaceService = game:GetService("MarketplaceService")
local AddHealthID = 20433249 --ENTER 
local AddSpeedID = 20438665  --PASS
local AddGearID = 21739855   --IDS
local AddGear2ID = 21739858   --IDS
local AddGear3ID = 21739864  --HERE
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
    end
    for i, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == AddHealthID then
                player.Character.Humanoid.MaxHealth = player.Character.Humanoid.MaxHealth + 50 --Adds 50 to their current health
                player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
            end
            if receiptInfo.ProductId == AddSpeedID then
                player.Character.Humanoid.WalkSpeed = player.Character.Humanoid.WalkSpeed + 15 -- Adds 5 to their current Walkspeed
            end
            if receiptInfo.ProductId == AddGearID then
                game.ReplicatedStorage.DualVenomshanks:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
                -- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
            end
            if receiptInfo.ProductId == AddGear2ID then
                game.ReplicatedStorage.GravityCoil:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
                -- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
            end
            if receiptInfo.ProductId == AddGear3ID then
                game.ReplicatedStorage.Jetpack:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
                -- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
            end
        end
    end
    PurchaseHistory:SetAsync(playerProductKey, true)    
    return Enum.ProductPurchaseDecision.PurchaseGranted 
end

And then this in starterpack so that the cash perk will work:

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")

CASHID = 00000000 -- Put the ID of the Developer Product here. Dont forget to erase the 0's.

MarketplaceService.ProcessReceipt = function(receiptInfo)
    local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_product_" .. receiptInfo.ProductId
    local numberBought = ds:IncrementAsync(playerProductKey, 1)
    for i,v in pairs (game.Players:GetChildren()) do
        if v.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == CASHID then


                lds = v:FindFirstChild("leaderstats")
                if lds ~= nil then
                    cs = lds:FindFirstChild("Coins") --Change to your leaderstat that you want it to add to.
                    if cs ~= nil then
                        cs.Value = cs.Value + 1000 --Change to the amount of Coins you want to add.
                    end
                end
            end
        end
    end
    return Enum.ProductPurchaseDecision.PurchaseGranted     
end


                -- Put this script in the Starter Pack when you are done editing it :)

There is one problem, the second script causes the top one not to work. Maybe because it is in starterpack. Help if you can because i dont know how to fix it....
