Script is pausing loops instead of ending them?

So I have a round based game and if all the players in a team die then it will break the for loop and continue. That's what I want it to do. What it's actually doing is pausing the timer for about 5 seconds and continue. Please help..!

-- the parts that really matter
                for countdown = 300,0, -1 do
	if script.endRound.Value == true then
		script.CountDown.Value = 0
		break
	end
	if game.Workspace.Radio.Activated.Value == true then
		wait(20)
		script.CountDown.Value = 0
		for _, v in pairs(Players:GetChildren()) do
			if v.TeamColor == BrickColor.new("Dark stone grey") then
				v.leaderstats.Cash.Value = v.leaderstats.Cash.Value + 50
			end
		end
		script.CountDown.Value = 0
		break
	end
	for _, v in pairs(Players:GetChildren()) do
		if v.TeamColor ~= BrickColor.new("Dark stone grey") then
			for _, v in pairs(Players:GetChildren()) do
				v:LoadCharacter()
				script.endRound.Value = true
				wait(5)
				script.endRound.Value = false
			end
		end
	end
	script.CountDown.Value = countdown
	wait(1)
end
