why wont alvinblox's tutorial go through?

I am watching one of alvinblox's tutorials and I can not figure out what the problem is. I hear --that alvinblox's tutorials are out of date so that could be the problem. can anybody figure out why it will not go through my functions.

 local replicatedStorage = game:GetService("ReplicatedStorage")
local remoteData = game:GetService("ServerStorage"):WaitForChild("RemoteData")

local cooldown = 1

replicatedStorage.Remotes.Lift.OnServerEvent:Connect(function(player)--this block is the error

    print("Fired")

    if not remoteData:FindFirstChild(player.Name) then return "NoFolder" end
    print("Got pass if statement")
    local debounce = remoteData[player.Name].Debounce
    print("Got pass the Debounce Varible")
    if not debounce.Value then
        print("got pass debounce if statement")
        debounce.Value = true

        player.leaderstats.strength.Value = player.leaderstats.strength.Value + 25 * (player.leaderstats.rebirths.Value + 1)
        print("got pass leaderstats")
        wait(cooldown)

        debounce.Value = false

    end

end)
print("Got to end")

local module = require(script.Parent:WaitForChild("ModuleScript"))
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

script.Parent.Activated:Connect(function()
    module.Lift()
end)

local module = {}
local replicatedStorage = game:GetService("ReplicatedStorage")

function module.Lift()

    replicatedStorage.Remotes.Lift:FireServer()

end

return module
