How to make a script continuously check?[unanswered]

I have this script here that I am using to "end the round." (Checks if the team "Survivors" has zero people) The problem is that it runs, but after that doesn't continuously check if it is true. I tried to add a while loop , but that doesn't seem to work. So how can I make it check until the statement is true?

function waitforwinner()
while wait() do
if #_G.getTeam(game.Teams.Survivors) == 0 then
		m = Instance.new("Message",Workspace)
			m.Text = "The final survivor was infected. Infected win !Once you respawn the round will begin!"
		wait(3)
	m:Destroy()		
			if first_infected.StarterGear.Revolver ~= nil then
				first_infected.StarterGear.Revolver:Destroy()
					game.Workspace.Field1.Parent = game.Lighting
					wait(3)
					game.Lighting.Field1.Parent = game.Workspace
					_G.blue()--global function makes everyone blue again
						if #_G.getTeam(game.Teams.Infected) == 0 then
		begin("The round has begun.",3)
		GiveGun()
		FirstInfected("A player has been randomly infected!",3)
		waitforwinner()
						end
			end
						
						elseif #_G.getTeam(game.Teams.Survivors) >= 1 then-- If time runs out do
							wait(400)
							m = Instance.new("Message",Workspace)
			m.Text = "Time has run out. Survivors win!"
		wait(3)
	m:Destroy()	
	end		
			if first_infected.StarterGear.Revolver ~= nil then
				first_infected.StarterGear.Revolver:Destroy()
				end
					game.Workspace.Field1.Parent = game.Lighting
					wait(3)
					game.Lighting.Field1.Parent = game.Workspace
					_G.blue()
						if #_G.getTeam(game.Teams.Infected) == 0 then
		begin("The round has begun.",3)
		GiveGun()
		FirstInfected("A player has been randomly infected!",3)
		waitforwinner()
						end				
end
end
waitforwinner()

Thanks!

P.S. This is in a function

Courntine.wrap.Function()

you need to put a while true do in there instead of while wait() do, like this :

function example()
gibba =  false
giff = true
while true do --<- c, not while wait() do
print"hello"
elseif gibba = false then print"hey"
end
example()

btw this is an example
