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 I hear --that alvinblox's tutorials are out of date so that could be the problem.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 replicatedStorage = game:GetService("ReplicatedStorage")

function module.Lift()
	
	replicatedStorage.Remotes.Lift:FireServer()
	
end

return module
