Hello!

I am trying to add sounds to website I built in Dreamweaver. The idea
is to make this webpage into a "soundboard", where the user can click
on little buttons and  soundbites plays.
 
So I've tried several different approaches to this problem and they
don't seem to work quite right. If you could respond with an actual
step-by-step, specific way of setting this up, instead of just links
to Dreamweaver tutorials, that would be much appeciated!

(1) what kind of sound files work(are compatible), and how big can
they be? (I tried .wav files, around 200-500k)
(2) how exactly do you set it up so that when you click on the button
it plays the sound? (I tried linking it directly to the sound file,
which didn't work, and also I tried setting it up as a "behavior" in
Dreamweaver, but that also didn't work.

Lastly, does it have anything to do with certain plug-ins/features
that browsers need to have?

Thanks!
