    if(counterForGoToMainPage == 0){
      clearInterval(productInterval);
      counterForGoToMainPage = 15;

  function countTouches(event) {
  var x = event.touches.length;

      counterForGoToMainPage = 15;
      productInterval = setInterval(function(){
         startTimer();
      },1000);
    }
