It makes the script shorter and easier to read but I don’t know why, I don’t recieve anything

On line 14, replace the game.Players.LocalPlayer with game.Players:GetPlayerByUserId(receiptInfo.PlayerId). I’m assuming this script is a server script since it is located in the ServerScriptStorage, and accessing local players from there usually cause problems.

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local StarerGui = game:GetService("StarterGui")

local productID = 1347531300

local function ProcessReceipt(ReceiptInfo)
	print("Proccessing reciept")
	
	local Player = Players:GetPlayerByUserId(ReceiptInfo.PlayerId)
	if not Player then
		warn("Player is not ingame, not yet proccessed payment")

	end
	
	print(string.format("%s has %i cash, incrimenting by %i", Player.Name, Player.leaderstats.Cash.Value, StarerGui.Utilities.UIs.ShopMain.InFrame.ButtonsFrame.Cash.Shadow1.BuyButton1.InfoLabel.ChangeGiveCash.GiveCash.Value))
	
	Player.leaderstats.Cash.Value += StarerGui.Utilities.UIs.ShopMain.InFrame.ButtonsFrame.Cash.Shadow1.BuyButton1.InfoLabel.ChangeGiveCash.GiveCash.Value
	print("Purchase granted")
	return Enum.ProductPurchaseDecision.PurchaseGranted
end

MarketplaceService.ProcessReceipt = ProcessReceipt

Try this and look at your output and tell me what it spat out.

Well then, clearly the reason why your cash is not changing is because
StarerGui.Utilities.UIs.ShopMain.InFrame.ButtonsFrame.Cash.Shadow1.BuyButton1.InfoLabel.ChangeGiveCash.GiveCash.Value equals 0

But it has a value…

How is that possible?

It’s not equal to 0, but, when I changed the script with something else like
Player.leaderstats.Cash.Value += Player.leaderstats.Cash.Value
then it worked.
So i think the problem is that the game doesn’t read a number value in the Starter GUI?

Don’t change values in StarterGui. They’re replicated to the player when they join.

Okay so I changed my script and put it in Workspace but now I have the error:

Here’s the script:

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function()	
	while wait(.5) do
		local formula = ((game.Players.LocalPlayer.leaderstats.Multiplier.Value/1.5)*game.Workspace.ServerMulti.OldValue.Value*5)/10  -- Multi.Value * ServerMultiplier * EventMultiplier/10
		if game.Workspace["Usefull Informations"].PlayerInformations.VIP.Value == true then
			formula = formula*5
		end
		script.GiveCash.Value = formula*100*(3600/2)
	end
end)

LocalPlayer only exists within LocalScripts. Also, don’t put these kinds of scripts in the Workspace.

Also, what’s the loop for? I’m very sure you don’t need it.

Is the Folder’s name leaderstats?

If no, add it.
If yes, it might be a bug. Or change it to :WaitForChild("leaderstats").

Because it updates depending on a stat a player has called Multiplier, and it changes in the game. So the formula has to update every time

Yes it is, the problem doesn’t come around here apparently

Then use RunService instead of yielding the whole script with a loop

Okay, by the way you said that I shouldn’t put these types of script in the Workspace, then where do you think I should put them?

It doesn’t actually matter. You can put it in ServerSctiptService, but it’s purely aesthetic.

small correction, I’d avoid placing scripts in workspace unless they really need to, simply because most scripts don’t need to be replicated to the client. (the name, classname etc, i am aware source isnt replicated)

Okay so I took the advice of everyone but I’m facing an issue.
The script doesn’t give the cash to the player but it works, basically I tell the script to give cash depending on a numbervalue placed in the Workspace, but I don’t know why, this number value is equal to 0 for the game. Lemme show you:

I made a script that print’s the NumberValue’s Value:
print(game.Workspace["Usefull Informations"].DevProducts.Cash.Cash1.Value)

And here is the number value in game:

It prints out 0, I don’t know why. How could I fix that?

Could you send your scripts as they currently are and I’ll give you the fix? Just so I don’t need to piece together what changes have/haven’t been made.

It won’t really be replicated to the client. The ‘Script’ object will, but only as a hollow shell comprised of a Name, ClassName, LinkedSource, and Disabled property. It will take up so little data that it won’t matter. The source of the script (which takes up far more space) won’t be replicated because server side script sources are never sent to the client.
