RemoteFunction sending arguments?

I'm trying to send the name of a audio to a local script so it can read the timelength, This is the second day I have been trying to get this stupid crap to work.

I keep getting: bad argument #2 to '?' (string expected, got nil)

Local:

events.Senders.LocalTimeLength.OnClientInvoke = function(plr, namasde)
    for i,v in pairs (board["Main(EDIT)"][namasde]:GetChildren()) do
        if v.IsPlaying == true then
            return v.TimeLength
        end
    end
end

Server:

wait(script.Parent.Events.Senders.LocalTimeLength:InvokeClient(game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())],  script[name].Name))

(name is not a object it's the name property of an object)
