Win32Lib is choking.  Here's the complete program:
[begin code]

constant songPix = create (Pixmap, "My Pixmap", Win, 0, 0, 450, 50, 0)
------------------------------
constant PixLabel = create( CText, "", songPix, 0, 0, 360, 14, 0)
--The program is choking on this line, with a Win32Lib error:
--Errorcode: 432

        count += 1
        stripped_song = 
stripped_song[2..(length(stripped_song))]--Removes "xx."
        char = song_name[count..count]
      end while
  return stripped_song
end function

created correctly

	end while
end procedure

	end if
else

end if

end procedure

end procedure
