Hello. I’m getting the error *attempt to perform arithmetic (add) on number and Instance * coming from line 3 of this server script

Oh no...

The Code

game.ReplicatedStorage.Event.OnServerEvent:Connect(function(Player, Amount)
	
	Player.leaderstats.Coins.Value += Amount
end)
2

Can you print your Amount variable?

Could you show us your client-sided code? I presume that you have accidentally written:

-[[Path.to.RemoteEvent]]:FireServer(Player, Amount)

local Car = script.Parent.Parent.Object.Value

local Player = game:GetService("Players").LocalPlayer

local ReplicatedStorage = game:GetService("ReplicatedStorage")

Car:GetPropertyChangedSignal("Name"):Connect(function()
	
if Car.Name == "Destroyed" and Car.Destroyed.Value == false then
		
		local Amount = 100
		
		local Event = ReplicatedStorage.Event
		
		Event:FireServer(Player, Amount)

		Car.Destroyed.Value = true
	else
		return
			
   end	
end)

I assumed correctly.

RemoteEvent.OnServerEvent listeners automatically receive the Player instance of the client that called RemoteEvent:FireServer. Additional arguments follow:

local function OnServerEvent(Player, ...)

With the additional Player instance passed, Amount gets occupied by the instance.

See “Remote Functions and Events” for a refresher.

TL;DR: Remove your first argument to FireServer.

You dont need to put player as the first parameter in fireserver, because upon .OnServerEvent firing the player is the first parameter recieved

Client

RemoteEvent:FireServer(Amount)

Server

RemoteEvent.OnServerEvent:Connect(function(Player, Amount) -- PLayer is first parameter by default
end)
