Function mit Quicktime

[beatjunky99]

ich hb die Function mal ein bisschen überarbeitet, aber sie geht immernoch nicht... was ist los??

function showTime()
  {
  var timeend = document.mp3.GetEndTime();
  var timestayminu = parseInt(timeend - timestay);
  var timestaysec = parseInt((timeend - timestay - timestayminu)/1000);
  var vornull = ((timestaysec<10) ? "0" : "");
  var timestaymin = parseInt(timestayminu/60000);
  document.getElementById("timeTextMin").innerHTML = '' + timestaymin + ':';
  document.getElementById("timeTextSec").innerHTML = '' + vornull + '' +timestaysec + '';
  window.setTimeout("timer("+ timestaymin +","+timestaysec+")", 1000);
  }

function timer(timestaymin, timestaysec)
  {
  if (timestaysec>0) && (timestaymin>=0){
  timestaysec--;
  var vornull = ((timestaysec<10) ? "0" : "");
  document.getElementById("timeTextMin").innerHTML = '' + timestaymin + ':';
  document.getElementById("timeTextSec").innerHTML = '' + vornull + '' +timestaysec + '';
  window.setTimeout("timer("+ timestaymin +","+timestaysec+")", 1000);
  }
  else if (timestaysec=0) && (timestaymin>=0){
  document.getElementById("timeTextMin").innerHTML = '' + timestaymin + ':';
  document.getElementById("timeTextSec").innerHTML = '00';
  var timestaysec = 60;
  timestaymin--;
  window.setTimeout("timer("+ timestaymin +","+timestaysec+")", 1000);
  }
  else {
  document.getElementById("timeTextMin").innerHTML = '0:';
  document.getElementById("timeTextSec").innerHTML = '00';
  }
  }
