Creating custom list (without UIListLayout)

[NinjoOnline]

I want to create a list, that updates automatically, based on its contents, however I can’t use UIListLayout as I can’t do tweening. So basically I add a new notification to the bottom, and I want all the ones above to tween up. However, that don’t happen at the moment

--// Create a notification prompt
local function CreateNotification(noticeType, notification)
	coroutine.wrap(function()
		if #Notices > 0 then -- More than 1 notice
			local Count = 0
			
			for i, v in pairs(Notices) do
				Count += 1
				local Notice = Frame:FindFirstChild(i)
				if Notice then
					Notice:TweenPosition(UDim2.new(0, 0, Count / 3, 0), Enum.EasingDirection.Out, Enum.EasingStyle.Linear, 0.25, true)
				end
			end
		end
		
		-- Create the new prompt
		local NewPrompt = Template:Clone()
		
		Notices[NewPrompt] = 1
								
		NewPrompt.Parent = Frame
		
		-- Tween in
		local TweenIn = TweenService:Create(
			NewPrompt,
			TweenInfo.new(0.5),
			{AnchorPoint = Vector2.new(1, 0.5)}
		)
		TweenIn:Play()
		
		wait(WaitTime)
				
		-- Tween out
		local TweenOut = TweenService:Create(
			NewPrompt,
			TweenInfo.new(0.5),
			{AnchorPoint = Vector2.new(0, 0.5)}
		)
		TweenOut:Play()
		TweenOut.Completed:Wait()
		
		Notices[NewPrompt] = nil -- Remove from Notices table
		
		NewPrompt:Destroy()
	end)()
end

I think this is similar to something I’ve done before. I used a UIListLayout with invisible framesm then tweened frames that you could see to the absolute positions.
(Sorry if my grammars bad, I’m really tired atm)
