How do I fix a GUI problem?..

So Im making a mini game and when I tell the GUI to change it wont.. every time you die it dose but I want the gui to change smoothly.. help please.

minigames = game.Lighting.Minigames:GetChildren()
h = game.StarterGui.Ament.TextLabel

while true do
	
	if game.Players.NumPlayers > 1 then
		h.Text = "Choosing Game..."
		wait(3)
		ranGame = math.random(1, #minigames)
		gameChosen = minigames[ranGame]
		h.Text = "Minigame Chosen: " .. gameChosen.Name
		wait(3)

You're changing the StarterGui object. StarterGui basically clones and resets Guis in a Player's PlayerGui on reset. Which means, anything you add or change in StarterGui will not appear after you respawn. A way you can avoid this is using a for loop to go through all players of the game, and change that label.

minigames = game.Lighting.Minigames:GetChildren()

while true do

    if game.Players.NumPlayers > 1 then
        for _,v in pairs(game.Players:GetChildren()) do --:GetChildren sets up a table of objects (or the players), the for loop will go through all players until it is done.
			v.PlayerGui.Ament.TextLabel.Text = "Choosing Game..." --PlayerGui is what is displayed to the user in real time, changes here are seen.
		end
        wait(3)
        ranGame = math.random(1, #minigames)
        gameChosen = minigames[ranGame]
		for _,v in pairs(game.Players:GetChildren()) do --Same thing here.
			v.PlayerGui.Ament.TextLabel.Text = "Minigame Chosen: " .. gameChosen.Name
		end
        wait(3)
