Im a starter in roblox scripting and i want to know what and where i need to add to makes this values really changes

[SANYAA_BL9 (BetterLateThanNever)]

stats script:

game.Players.PlayerAdded:Connect(function(player)
	local stat = Instance.new("Folder", player)
	stat.Name = "stats"
	
	local money = Instance.new("IntValue")
	money.Name = "Money"
	money.Value = 0
	money.Parent = player.stats
	
	local Multiplayer = Instance.new("IntValue")
	Multiplayer.Name = "Multi"
	Multiplayer.Value = 1
	Multiplayer.Parent = player.stats
	
	while true do
		task.wait(1)
		money.Value += 1 * Multiplayer.Value
	end
	
end)

upgrade button script:

local Player = game.Players.LocalPlayer
local Money = Player.stats:FindFirstChild("Money")
local Multi = Player.stats:FindFirstChild("Multi")

local ReplicatedStorage = game:WaitForChild("ReplicatedStorage")
local Remotes = ReplicatedStorage:WaitForChild("Remotes")
local Event = Remotes:WaitForChild("DoubleMoneyGainEvent")

local screenGUI = script.Parent
local GuiHolder = screenGUI.GuiHolder
local UpgradesHolder = GuiHolder.UpgradesHolder
local StatsHolder = GuiHolder.StatsHolder

local DoubleMoneyGainButton = UpgradesHolder.DoubleMoney.UpgradeButton

local function DoubleMoneyGain()
	local NumberOfUpgrades = DoubleMoneyGainButton.NumberOfUpgrades
	if NumberOfUpgrades.Value == 0 and Money.Value >= 5 then
		Money.Value -= 5
		Multi.Value *= 2
		NumberOfUpgrades.Value += 1
		Event:FireServer()
	end
end

DoubleMoneyGainButton.MouseButton1Click:Connect(DoubleMoneyGain)

So whats working and whats not? (e.g is the money value increasing in leaderstats) because I cant really tell whats what like is “holder” supposed to be a text label or frame?

[SANYAA_BL9 (BetterLateThanNever)]

everything works just when im cluck upgrade button my cash get - 5 but after a second it goes to value it was and didn’t get a multiplayer

[urgentnotice]

then its probably a problem with replicated storage?
im also new so im not 100% sure

@SANYAA_BL9

local ReplicatedStorage = game:WaitForChild("ReplicatedStorage")
local Remotes = ReplicatedStorage:WaitForChild("Remotes")
local Event = Remotes:WaitForChild("DoubleMoneyGainEvent")

Idk the reason for using :WaitForChild instead of :GetService because I’ve always used :GetService(“ReplicatedService”)
same thing for your remotes and events, I would just index them normally

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Remotes = ReplicatedStorage.Remotes
local Event = Remotes.DoubleMoneyGainEvent

[SANYAA_BL9 (BetterLateThanNever)]

@urgentnotice

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Remotes = ReplicatedStorage.Remotes
local Event = Remotes.DoubleMoneyGainEvent

nah there is something else its still doesnt work

[TomPlays63 (Tom)]

The player isn’t earning any money because 1x1 = 1

[SANYAA_BL9 (BetterLateThanNever)]

no he earns money and problem absolutely not in this

[urgentnotice]

@SANYAA_BL9

		Event:FireServer()

whats this for? is there another server script because i dont see this event being recienved on your first script

[SANYAA_BL9 (BetterLateThanNever)]

this is RemoteEvent From ReplicatedStorage

[TomPlays63 (Tom)]

I never noticed you using += 1 then

[urgentnotice]

yeah you fired the remote event from client but the server should do something once it recieved it

[SANYAA_BL9 (BetterLateThanNever)]

so what i need to do???

[urgentnotice]

@SANYAA_BL9

local function DoubleMoneyGain()
	local NumberOfUpgrades = DoubleMoneyGainButton.NumberOfUpgrades
	if NumberOfUpgrades.Value == 0 and Money.Value >= 5 then
		Money.Value -= 5
		Multi.Value *= 2
		NumberOfUpgrades.Value += 1
		Event:FireServer()
	end
end

we can just code the logistics in the server script so change this to

local function DoubleMoneyGain()
	local NumberOfUpgrades = DoubleMoneyGainButton.NumberOfUpgrades
		NumberOfUpgrades.Value += 1
		Event:FireServer()
	end
end

then add the part we removed to the server script (add this to the top of the server script)

Event.OnServerEvent:Connect(function(player) 
	Money.Value -= 5
	Multi.Value *= 2
end)

[SANYAA_BL9 (BetterLateThanNever)]

Nah it giving me error: OnServerEvent can only be used on the server - Client - LocalScript:24

[SANYAA_BL9 (BetterLateThanNever)]

ok i almost got it im switched script from local to server
im just need to find where do i put MouseButton1Click and RemoteEvent

local ReplicatedStorage = game:WaitForChild("ReplicatedStorage")
local Remotes = ReplicatedStorage:WaitForChild("Remotes")
local RemoteEvent = Remotes:WaitForChild("DoubleMoneyGainEvent")

local screenGUI = script.Parent
local GuiHolder = screenGUI.GuiHolder
local UpgradesHolder = GuiHolder.UpgradesHolder
local StatsHolder = GuiHolder.StatsHolder
local DoubleMoneyGainButton = UpgradesHolder.DoubleMoney.UpgradeButton

--DoubleMoneyGainButton.MouseButton1Click:Connect(function(player)
	local Money = player.stats:FindFirstChild("Money")
	local Multi = player.stats:FindFirstChild("Multi")

	local NumberOfUpgrades = DoubleMoneyGainButton.NumberOfUpgrades
	if NumberOfUpgrades.Value == 0 and Money.Value >= 5 then
		Money.Value -= 5
		Multi.Value *= 2
		NumberOfUpgrades.Value += 1
	end
end)

--where do u need to put those?
--RemoteEvent:FireServer()
--DoubleMoneyGainButton.MouseButton1Click:Connect(function(player)
	end
end)

[urgentnotice]

nooooooooooooo
remote event is used to communicate between server and client scripts
idk why dev forum send the notification so late
I dont think you can access guis through server scripts so your new script wont work

@urgentnotice

Event.OnServerEvent:Connect(function(player) 
	Money.Value -= 5
	Multi.Value *= 2
end)

you have to put this inside of the server script!!! thats what i said!!

[urgentnotice]

@urgentnotice

Event.OnServerEvent:Connect(function(player) 
	Money.Value -= 5
	Multi.Value *= 2
end)

this is the only part that needs to be inside of the server script
