Hi all i have a little problems…
I followed the MP3 player tutorial on this website (great site, video tutorials)
Everything runs smoothly, but I noticed that the tutorial maker did not include a “Previous song” button to go back to the previous song. He has a play/pause button and a next button. I’m wondering if someone can help me create a “previous song” button. Here is the code
[SIZE=2]//Sets up the sound[/SIZE]
[SIZE=2]var s:Sound = new Sound();[/SIZE]
[SIZE=2]s.onSoundComplete = playSong;[/SIZE]
[SIZE=2]//sets volume to 75%[/SIZE]

[SIZE=2]s.setVolume(vol);[/SIZE]

When i test movie, the very first song in the XML plays. I click the “Previous song” button to jump to the very last song i the XML but it doesnt work… it comes up with error message#
Error opening URL "file:///G|/Multi%2DMedia%20System/undefined"
But when i click the “Next song” button and listen to a song halfway in the XML, THEN click the “Previous song” button, it does go back until i get to the first song.
I was hoping someone could help me find a way of playing from the very last song in the XML after i clicked the “Previous song” button from the first song in the XML.
