Need Help With a Script That Opens a Gui When Countdown Finishes?

OK So on line 69 I am having a problem with calling the Gui fro StarterGui. No matter what I do it will not make the Gui appear when the countdown is over.

Currently on line 69 I have game.StarterGui.Waves.Waves.Enabled = true I have also tried game.StarterGui.Waves.Waves.Frame.Visible = true amongst other calls to try to get it to show up.

I am thinking this is because it is not pointing toward the PlayerGui and instead is pointing to the Gui located in the StarterGui, However I have no idea how I to point it to a player without it being a local script. Can soeone help me revise this so it will show the Gui in this server script. Thanks in advance, any help is appreciated

game.ServerScriptService["Wave1 - PathFind"].ZombieScript.Disabled = false
game.ServerScriptService["Wave1 - PathFind"].ZombieScript1.Disabled = false
game.ServerScriptService["Wave1 - PathFind"].ZombieScript1d3.Disabled = false

disasters = {"Wave0"} -- This is where you list the names models that you want to use for disasters.
-- Disaster names are case-sensitive and all disaster models must be in the lighting

countdownTime = 5 -- The ammount of time to wait between each disaster.

countdownMessage = "You have %s to prepare." -- The message displayed between disasters. %s will be replaced with the number of seconds left.
disasterMessage = "Wave 1" -- The message displayed when a disaster occurs. %s will be replaced with the disaster name. Set to nil if you do not want a message

-- Unless you know what you are doing, please leave the below code alone.
items = {}
local w = game.Workspace:getChildren()



for i=1, #disasters do
	local item = game.ReplicatedStorage.Wave1:findFirstChild(disasters[i])
	if item ~= nil then
		item.Parent = nil
		table.insert(items, item)
	else
		print("Error! ", disasters[i], " was not found!")
	end
end

function chooseDisaster()
	return items[1]
end

function sethint(text)
	local hint = game.Workspace:findFirstChild("hint")
	if (hint ~= nil) then
		hint.Text = text
	else
		print("Hint does not exist, creating...")
		local h = Instance.new("Hint")
		h.Name = "hint"
		h.Text = text
		h.Parent = game.Workspace
	end
	--print("Hint set to: ", text)
end

function removeHint()
	local hint = game.Workspace:findFirstChild("hint")
	if (hint ~= nil) then hint:remove() end
end

function countdown(time)
	sethint(string.format(countdownMessage, tostring(time)))
	while (time > 0) do
		wait(1)
		time = time - 1
		sethint(string.format(countdownMessage, tostring(time)))
	end
	removeHint()
	return true
end

while true do
	countdown(countdownTime)

	local m = chooseDisaster():clone()
print("This is working")
	
 game.StarterGui.Waves.Waves.Enabled = true

print("This is working 2")

		wait(3)
		print("This is working 3")


	local m = chooseDisaster():clone()
	m.Parent = game.Workspace
	m:makeJoints()




	
break
end

StarterGui is what goes into the PlayerGui when the player joins. So to enable the Gui you must access the PlayerGui. Like this:

Player.PlayerGui.Waves.Waves.Enabled = true

If you are trying to enable the gui for all players, this should work.

	for index, child in pairs(game.Players()) do
child.PlayerGui.Waves.Waves.Enabled = true
end

Hey CrazyRoblots, the guys there up already said the answer, but I just wanna tell you that's a bad practice. You shouldn't put the 'ScreenGui' class' 'Enabled' bool to 'true'. Inside that ScreenGui, there has to be childs, like Frames, TextLabels, or something like that. You should turn every ScreenGui childs 'Visible' bool (which is a property) to false, and then, in the script, change it to true.

For example, you have this

game > StarterGui > ExampleGui > ExampleFrame

you should start with ExampleFrame's 'Visible' bool on 'false' and then, in a local script,

game.Players.LocalPlayer.PlayerGui.ExampleGui.ExampleFrame.Visible = true

and not start ExampleGui's 'Enabled' bool on 'false' and then turn it on 'true', like

game.Players.LocalPlayer.PlayerGui.ExampleGui.Enabled = true

Hope I could, somehow, help.
