Gui works in studio but in game?

repeat wait() until game.Players.LocalPlayer
local i = script.Parent
local map = workspace.Stadium.sa
local gui = script.Parent.Parent.Parent
local tele1 = game.Lighting.Tele1
function onButtonClicked()
    local plr = game.Players.LocalPlayer
    local character = plr.Character
if (plr and character ~= nil) then
    character:MoveTo(map.Position)  
    tele1:Clone().Parent = plr.PlayerGui
    script.Parent.Parent.Parent:Destroy()
end
    end
i.MouseButton1Down:connect(onButtonClicked)

The difference between studio and in game mode is that in studio, the player loads immediately. In game, the player takes a little bit to load. So, if we keep waiting until the script detects a Player, this can be resolved.
