The Intermission function does not update on the GUI when I run the script. Can someone help me?

local players = game:GetService("Players")

local function Intermission(player)

local BeginningText = game.Players.player.PlayerGui.ScreenGui

game.StarterGui.ScreenGui.Enabled = true

    wait(1)
    BeginningText.TextLabel.Text = "Beginning In 4"
    wait(1)
     BeginningText.TextLabel.Text = "Beginning In 3"
    wait(1)
     BeginningText.TextLabel.Text = "Beginning In 2"
    wait(1)
     BeginningText.TextLabel.Text = "Beginning In 1"
    wait(1)
     BeginningText.TextLabel.Text = "Beginning In 0"
end

    local function playerwait(player)
          if #players:GetPlayers() > 2 then 
        game.StarterGui.WaitingForPlayer.Enabled = false

        wait(1)

        Intermission(player)
    end
        end

game.Players.PlayerAdded:Connect(playerwait)
