Help with creating a function

Noob question, help needed. I would like to write a general sound function to use in my program, but after many unsuccessfully attempts I gave up so any help on this is much appreciated... What I'm after is a function that I can call with 3 input parameters:

1. Name of loaded sample
2. Which of the allocated channels it should be played in.
3. Its volume.

Here is a dummy non-working example of what I'm looking for.. Hopefully you know what I mean ;-)
...
...

Global Volume#
Global SFXChannel:TChannel = AllocChannel()
Global SND_Boom:TSound = LoadSound ("Data/Sounds/Boom.wav")

..
..

Play_Sound (SND_Boom,SFXChannel,.9)
..
..

Function Play_Sound (Sample,Channel,Volume)

If Channel <> Null Then
Channel.SetVolume(Volume)
PlaySound(Sample, Channel)
EndIf

EndFunction

try passing parameters to your function like this

Function Play_Sound (Sample:TSound,Channel:TChannel,Volume#)

if it doesn't work let me know what kind of error you are getting. everything else looks good.
