Need changes to this perl script

This cgi script is running now on my server

                  as you see it takes a password and delivers a .wav file

                  except right now the file comes up as text in the browser

                  i need the exact changes that would need to be made

                  to make the .wav file prompt the

                  user for a "save as" and and then allow for download

                  of the song??

                  exact detailed changes please!!!

I Need You To MAKE THE CHANGES IN THE SCRIPT AND REPRINT

THE CHANGE.... it's no use just telling me where

because i already tried that and always get "server error"

so please make the changes and REPRINT the script here

thanks
