Minigame script problem.

Hi. I've created an automated minigames script, which has a few problems. The players respawn in some random place the first time, then die, then spawn at the right place, which is bad, since I want them to be spawned at a spawn location first time round. Also, the timer doesn't work. Also, another glitch is that sometimes, the player repeatedly spawns outside the map.

Thank you. The output doesn't say anything but this "Players.Player1.PlayerGui.timer.Frame.timetext.Script:42: attempt to index field 'Parent' (a nil value)"

function respawn()
    for i, v in pairs(game.Players:GetPlayers()) do
        coroutine.resume(coroutine.create(function()
            v:LoadCharacter()
            end))
        end
    end


function timer()
    respawn()
if game.Workspace.MapHolder:GetChildren()[1]~= nil then
        for i = timelim, 0, -1 do
            wait(1)
            script.Parent.Text = i -- this line
            end
                script.Parent.Text = "Time up!"
                for i,v in pairs(game.Players:GetPlayers()) do
                    if v.TeamColor ~= BrickColor.new("Bright yellow") then
                        v.TeamColor = BrickColor.new("Bright yellow")
                        v:LoadCharacter()
                        wait(5)
                        if game.Players.NumPlayers>=reqplr then
                            wait(3)
                randommap()
                    end
                end
            end
        end
end
