check the filereference class.
Sorry, I don't know what that means. Would it hurt to walk me through it?
i'll walk you through how to learn flash. in this particular situation:
open the flash help files, click on actionscript 2.0 language reference, click on actionscript classes, click on filerefence and read. in particular, you'll want to read about the download() method of the filereference class.
if you have difficulty following the explanation, scroll towards the bottom and you'll often see code snippets that you can copy and paste, change a few things and suit your situation.
As far as I can make out from there, it's too complicated a procedure and doesn't do what I wanted.
Turns out php is a much simpler solution so I'll go with that.
Thanks though, for telling me to read the manual. Really helpful of you.
