Inside the script is an Gui this gui have to pop-up when the time is ready (Multi guis will be added in the script but one gui is already not working, help what did i wrong?) Can someone help ? Thanks. (All players need get the gui on the screen on the same time.)

local EventsGuii = script.EventsGui

while true do
    wait (5)
    local human = game.Players:GetPlayerFromCharacter
    human:WaitForChild("PlayerGui"):FindFirstChild("EventsGui")
        local newGui = EventsGuii:Clone()
        newGui.Parent = human.PlayerGui
        newGui:remove()
    end
    wait (5)
    end)
end
