Gui worked but after trying to get FE enabled for it it just stopped working?

I'm really terrible at FE and i cant get it to work for my gui.(i'm also pretty new to scripting) so it's supposed to be a round script and it worked

(both scripts are in startergui)

LocalScript

local play = game.Players.LocalPlayer

game.ReplicatedStorage.Intermis.OnClientEvent:Connect(function()
while true do 	
			script.Parent.TextLabel.Text = "Intermission = "..script.Parent.Int.Value
			script.Parent.Int.Value = script.Parent.Int.Value - 10
			wait(1)
	if script.Parent.Int.Value == 0 then
		for _,player in pairs (game.Players:GetPlayers()) do		
			if player.Character then			
			player.Character:MoveTo(Vector3.new(game.Workspace.tele.Position))
			script.Parent.TextLabel.Visible = false
	if script.Parent.TextLabel.Visible == false then
		for  i = 600, 1, -1  do
			script.Parent.time.Visible = true
			script.Parent.time.Text = "Time Left = "..i
			wait(1)
	if i == 1 then
			play.Character:MoveTo(Vector3.new(197.927, -48.632, -116.923))
			script.Parent.Int.Value = 30
			script.Parent.TextLabel.Visible = true
			script.Parent.time.Visible = false
							end
						end
					end
				end
			end
		end
	end
end)

Script

game.Players.PlayerAdded:Connect(function(gof)
	game.ReplicatedStorage.Intermis:FireAllClients(gof)
end)

I know i got something wrong
