I want it to spawn npc's while the text label says "Game", but when it says "Intermission", I want the zombies to stop spawning

If anyone can help I would really appreciate it! Thanks!

local NPC = game.ReplicatedStorage.Zombie 
local spawner = script.Parent
GameTime = game.StarterGui.Timer.Frame.TextLabel
	
if GameTime.Text == "Game" then
	repeat
		local Clone = NPC:Clone()
 		Clone.Torso.CFrame = spawner.CFrame 
 		Clone.Parent = workspace
 		wait(2)
	until
			GameTime.Text == "Intermission"
end
