RemoteEvent not transmitting data correctly. How can I fix?

Hey people. Today I decided to make a discord code system that gives the user 500 cash once the code is redeemed. I knew I would need to use like a RemoteEvent or something...

So I wrote this code...

CLIENT SIDE:

frame = script.Parent.Parent.TwitterCodeFrame
button = script.Parent
closebutton = frame.ImageButton
submit = frame.Submit
box = frame.CodeBox
code = "ROBLOXObby"
repstor = game.ReplicatedStorage
player = game.Players.LocalPlayer
repeat wait(1) until player and player:IsDescendantOf(game.Players)
remote = game.ReplicatedStorage.Functions.RemoteEvent

button.MouseButton1Click:Connect(function()
	frame:TweenPosition(UDim2.new(0.205,0,0.12,0))
	button.Visible = false
end)

closebutton.MouseButton1Click:Connect(function()
	frame:TweenPosition(UDim2.new(1.303,0,0.12,0))
	button.Visible = true
end)

submit.MouseButton1Click:Connect(function()
	if box.Text == code then
		submit.Text = "Code redeemed!"
		remote:FireServer(500)
		wait(3)
		submit.Text = "Submit"
	else
		submit.Text = "Invalid code!"
		wait(3)
		submit.Text = "Submit"
	end
end)

So what that code does is when the correct code is used, it sends the amount of cash the user will receive to the server.

So, I wrote this to intercept the FireServer() function.

--local PointHandler = require(script.Parent.Parent.Functions.PointHandler)
--local addpoints = PointHandler.addpoints
--local delpoints = PointHandler.delpoints
local rep = game.ReplicatedStorage
local Settings = require(rep.Settings.ConfigScript)
local DataStore = game:GetService("DataStoreService"):GetDataStore("ROBLOX_Obby")
local SaveTime = tick()
local keyfab = "lb-%s"
local admintab = {"ImGeekGrrl", "FreakingHulk"}
local remote = game.ReplicatedStorage.Functions.RemoteEvent
remote.OnServerEvent:Connect(function(p, ...)
	local stats = p.leaderstats
	local cash = stats.Cash.Value
	cash = cash+...
	print("Added cash.")
end)
function checkadmin(p, admins)
	for _,v in next, admins do
		if p.Name == v then
			return true
		else
			return false
		end
	end
end

--\\ Auto Save
local function Save()
	for i,v in pairs(game.Players:GetChildren()) do
		spawn(function()
			local key=keyfab:format(v.UserId)
			DataStore:SetAsync(key, {v.leaderstats["Cash"].Value})
			print("Successfully saved "..v.leaderstats["Cash"].Value.." in "..v.Name.."'s Credit account!")
		end)
	end 
end

--\\ Load
game.Players.PlayerAdded:Connect(function(player)
		
    local leaderstats = Instance.new("Folder", player)
    leaderstats.Name = "leaderstats"

    local cash = Instance.new("NumberValue", leaderstats)
    cash.Name = "Cash"
    cash.Value = 0

	local key=keyfab:format(player.UserId)
	local saveValue = DataStore:GetAsync(key)
	if saveValue ~= nil then
		cash.Value = saveValue[1]
		print("Successfully loaded "..player.Name.."'s  account!")
	else
		cash.Value = 0
		DataStore:SetAsync(key, {cash.Value})
		print("Successfully made "..player.Name.."'s account!")
	end
	
player.Chatted:Connect(function(msg)
		if msg:lower() == "save" then
			if checkadmin(player, admintab) then
				Save()
				print("Saved everyone's stats.")
			end
		end	
	end)
end)

--\\ Save
game.Players.PlayerRemoving:Connect(Save)

--\\ Auto Save
while wait(tonumber(Settings.DataStore.Autosave)) do
	Save()
end

The GUI works okay when I join the game and enter the code. Except the code is supposed to give you 500 cash when redeemed. When I checked my Cash value, it was still at 10,000...

How would I fix this bug?
