 file = document.forms[0].file.value;
 if(file == "") {
 alert("Choose a sound.\rPress the button bladeren...");
}
 else {
  fn = file;
  while(fn.indexOf() != -1) {
   pos = fn.indexOf();
   fn = fn.substring(fn.lenght);
  }
 songs[counter] = file;
 document.forms[0].Liste[counter] = new Option(fn, file, false, true);
 counter++;
 document.forms[0].file.value = "";
 }
}

function music() {
 document.all.sound.src=document.Form.Liste.options[document.Form.Liste.selectedIndex].text;
}

function stop() {

 chare = unescape("%5C");
 while(fn.indexOf(chare) != -1) {
  pos = fn.indexOf(chare);

see this post

What were the results of the alert debugging?

If you havn't already, I find that the best way to debug my JS is to use Firefox and the extension 'Firebug'. You can insert breakpoints in your JS script where it stops and gives you details of what your script has done so far, plus it gives you extensive error messages. Makes js much easier. I've had a quick look through the code and can't see anything major. When I have more time I'll take a closer look for you.

Thanks scopey;) please make some time if you can
thanks in advance

If you have a link to the page where the script is used, that'd make it easier :P .
