how would i get this function to repeat
[lua]
local clockText = display.newText(“20:00”, 160,30)
local secondsLeft = 20 * 60
local function updateTime()
secondsLeft = secondsLeft - 10
local minutes = math.floor( secondsLeft / 60)
local seconds = secondsLeft % 60
local timeDisplay = string.format("%02d:%02d", minutes, seconds)
clockText.text = timeDisplay
if timeDisplay == “19:00” then
composer.gotoScene(“menu”)
end
end
local countDownTimer = timer.performWithDelay(1000, updateTime, secondsLeft)
sceneGroup:insert(clockText)
[/lua]
