#1

I can’t find the error

error: attempt to index global “event” (a nil value)

  local W = display.contentWidth local H = display.actualContentHeight   local seconds = 0 local secondsT = display.newText(seconds, W/2,0,"Arial",40 ) local function time()  seconds = seconds+1  secondsT.text = seconds end local tempo = timer.performWithDelay( 1000, time,0) timer.pause( tempo ) local function tempoS (e)   if event.phase == "began" then   timer.resume( tempo ) end end Runtime:addEventListener( "touch", tempoS )  
#2

Inside :

local function tempoS (e)
  if event.phase == “began” then
  timer.resume( tempo )
end

Change  tempoS (e) by  tempoS (event)

#3

Inside :

local function tempoS (e)
  if event.phase == “began” then
  timer.resume( tempo )
end

Change  tempoS (e) by  tempoS (event)
