So with my developer products they change the value of my coins (stat) in my game but after I leave and come back they aren't saved by the other script?

Save/Load Datastore

-- Player Profile creator
	local DataStore = game:GetService("DataStoreService"):GetDataStore("PlayerStats")
	
game.Players.PlayerAdded:connect(function(plr)
	local profile = Instance.new("Folder")
	profile.Parent = game.Workspace.PlayerProfiles
	profile.Name = plr.Name
	
	local profile2 = Instance.new("NumberValue")
	profile2.Name = "Treasure"
	profile2.Parent = profile
	
	local profile3 = Instance.new("NumberValue")
	profile3.Name = "SavedTreasure"
	profile3.Parent = profile
	
	local p22 = Instance.new("NumberValue")
	p22.Name = "Coins" -- value changed by dev products
	p22.Parent = profile
	
	local p33 = Instance.new("BoolValue")
	p18.Name = "TwoSeaterDinghy"
	p18.Parent = profile

	local p34 = Instance.new("BoolValue")
	p18.Name = "SpeedDinghy"
	p18.Parent = profile

		
	--loading stats
	
--plr:WaitForDataReady()
wait(2)
local stats2 = game.Workspace.PlayerProfiles:FindFirstChild(plr.Name):GetChildren()
for i = 1, #stats2 do
stats2[i].Value = DataStore:GetAsync(stats2[i].Name)
print(stats2[i].Value)
end
end)



-- Profile deleter

function DeleteProfile(profile)
	
local Profiles = game.Workspace.PlayerProfiles

	Profiles:FindFirstChild(profile):Destroy()
end



game.Players.PlayerRemoving:connect(function(plr2)
--	plr2:WaitForDataReady()
	--wait(2)
	local stats = game.Workspace.PlayerProfiles:FindFirstChild(plr2.Name):GetChildren()
	
	for i=1, #stats do 
		print(stats[i].Name)
		DataStore:SetAsync(stats[i].Name, stats[i].Value)
		wait(1)
		DeleteProfile(plr2.Name)
	end
end)

-- Profile saver

Button Script : 

--Developer Product Gui Button simplified by TehRandoms--

local devProductId = 33248065	--The Developer Product ID if your item, must be a Product of the game place it is in
local player= script.Parent.Parent.Parent.Parent.Parent

--Well, as always, don't touch anything below if you have no idea what you are doing--

--Prompt Buy--
script.Parent.MouseButton1Click:connect(function()
	game:GetService("MarketplaceService"):PromptProductPurchase(player, devProductId)
end)

--Transaction--
local MarketplaceService = game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
MarketplaceService.ProcessReceipt = function(receiptInfo)
	for i, player in ipairs(game.Players:GetChildren()) do
		if player.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == devProductId then	
				game.Workspace.PlayerProfiles:FindFirstChild(player.Name).Coins.Value = game.Workspace.PlayerProfiles:FindFirstChild(player.Name).Coins.Value + 50	--You can put the event here.
				print(player.Name.."Bought Item "..devProductId)
			end
		end
	end
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.ProductId
		ds:IncrementAsync(playerProductKey, 1)	
	return Enum.ProductPurchaseDecision.PurchaseGranted
end
