Argument 2 missing or nil

[MaTeDii19]

Hello

So i followed a tutorial “How to make a Donation Board” and for some reason it doesn’t work. Whenever i’ll try to donate something or just clicka button nothing will happen and error pops up in output.

Output:

Argument 2 missing or nil - Server - Script:21
Stack Begin - Studio
Script ‘Workspace.DonationBoard.Main.SurfaceGui.Script’, Line 21 - Studio - Script:21
Stack End - Studio

Script:

local donateAmounts = {10, 25, 50, 100, 250, 500, 1000}
local ids = {1379354079, 1379354269, 1379354329, 1379354399, 1379354467, 1379354535, 1379354610}
local mps = game:GetService("MarketplaceService")
local dss = game:GetService("DataStoreService")
local ods = dss:GetOrderedDataStore("Donators")

for i, amount in pairs(donateAmounts) do

local donateButton = script:WaitForChild("DonateButton"):Clone()
donateButton.Amount.Text = amount .. " R$"
donateButton.Parent = script.Parent.Parent.Parent.Buttons.SurfaceGui.Frame.ScrollingFrame

end

game.ReplicatedStorage.Remotes.Donate.OnServerEvent:Connect(function(plr, button)

local amount = string.gsub(button.Amount.Text, " R$", "")
local id = ids[table.find(donateAmounts, tonumber(amount))]

mps:PromptProductPurchase(plr, id) -- Argument 2 missing or nil (line 21)

end)

The error is Appearing after click Donate Button

Uh, can you explain what you are trying to accomplish here:

game.ReplicatedStorage.Remotes.Donate.OnServerEvent:Connect(function(plr, button)

local amount = string.gsub(button.Amount.Text, " R$", "")
local id = ids[table.find(donateAmounts, tonumber(amount))]

mps:PromptProductPurchase(plr, id) -- Argument 2 missing or nil (line 21)

end)

Have you tried using a Positive Integer Mask instead of
local amount = string.gsub(button.Amount.Text, " R$", "")

Positive Integer Mask:

function PositiveIntegerMask(text)
	return text:gsub("%D+", "")
end

TextBox Masks and Formats

On-the-fly Masks and Formats for TextBoxes Did you know you can manipulate/restrict what a user types into a TextBox on the fly? This is commonly referred to as “masking.” I’ve seen a lot of games on here that could use it, and it’s actually quite easy to do. How it works: All you have to do is listen for the Text property to change using GetPropertyChangedSignal("Text"), then check the Text property and change it accordingly. For instance, if we want to only allow the user to type in positiv…

Something like this:

local amount = PositiveIntegerMask(button.Amount.Text)
local id = ids[table.find(donateAmounts, tonumber(amount))]

So i followed a tutorial “How to make a Donation Board”

uhh what is the tutorial link if you are following the tutorial

[MaTeDii19]

How to Make a DONATION BOARD | HowToRoblox

I made my own donation board but changed everything to work

[MaTeDii19]

I tried using that but it returns the same error

[VSCPlays]

well, there is the model and the scripts in the description though…

also, did you turn on Allow Third Party Sales?

[MaTeDii19]

Yes, I know there are scripts in the description and I copied them and still they don’t work.

Yes I did turn that on

I tried testing it using this:

local donateAmounts = {10, 25, 50, 100, 250, 500, 1000}
local ids = {1379354079, 1379354269, 1379354329, 1379354399, 1379354467, 1379354535, 1379354610}

function PositiveIntegerMask(text)
	return text:gsub("%D+", "")
end

local amount = PositiveIntegerMask("25 R$")
print(amount)
local id = ids[table.find(donateAmounts, tonumber(amount))]
print(id)

It seems to be working for me

[MaTeDii19]

It works!

I think I misspelled something before that’s why it didn’t work for the first time.
Thank you so much
