DataStore Issue

Help and Feedback Scripting Support
#1

Im a bit new with datastores. I want to have across experience donation board, so that everyone in every server can see how much robux is raised as a donation. I am using DataStore for that. Here is relevant part of the code of donating.

local MarketplaceService = game:GetService("MarketplaceService")
local DonationStore = game:GetService("DataStoreService"):GetDataStore("BardDonations")
--local xpupdate = game.ReplicatedStorage:WaitForChild("xpupdate")


local donate10ID = 1265124435
local donate100ID = 1265125116
local donate500ID = 1265125250


local function processReceipt(receiptInfo)
	
	local player = players:GetPlayerByUserId(receiptInfo.PlayerId)

	
	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
	
	
	
	if receiptInfo.ProductId == donate10ID then
		if player then
			game.Workspace.CurrentConst.Bar.Bard.Head.Goal:Play()
			local currentDon = DonationStore:GetAsync("BardDonations")
			DonationStore:UpdateAsync("BardDonations", currentDon+10)--DonationStore:SetAsync("BardDonations", 10)
		end
	end

It works and purchase processes, as the goal sound plays.

And this is the code inside a textlabel on which it should say how much is raised.

local Raised = script.Parent:WaitForChild("SurfaceGui"):WaitForChild("TextLabel")
local DonationStore = game:GetService("DataStoreService"):GetDataStore("BardDonations")
local currentDon = DonationStore:GetAsync("BardDonations")

Raised.Text = "Robux Raised:"..tostring(currentDon)


while task.wait(10) do
	local currentDon = DonationStore:GetAsync("BardDonations")

	Raised.Text = "Robux Raised:"..tostring(currentDon)
end

but it says “Robux Raised: Nil”, which i think means that i am updating datastore wrong.

But I cant figure out what am I doing wrong.

There are no errors in the output, if anyone has solutions, please help

You need to hook the second argument of UpdateAsync to a function

#3 
DonationStore:UpdateAsync("BardDonations", function()
    return currentDon+10
end)

Thank you! That worked. If i understand right how datastores work, now if someone donates in one server, during 10 seconds after that that donation will be visible on all other servers too, right?

Yep. as long as the loop stays running it’ll update the text
