Mp3 Upload

[alxsmth]

Hey,

I have been trying to get a php upload script to work which uploads an mp3 file to the server and then updates an xml playlist for a flash mp3 player.

It seemed to work once, but majority of the time i get the same error - "change permission to 777 failed". I am unable to change file permissions on my server but the fact that it worked once makes me think that this may not be the problem. Could anyone explain to me why this might be or suggest an alternate script i might use? Many thanks

here is the script.....

//Allow file delete? no, if only allow upload only.
