Stumped.

$num = 10;
function multiply()
{
$num = $num * 10;
}
multiply();
echo $num;

This prints "10" to the screen.

$num = $num * 10;
echo $num;

But this prints "0".

Why is that?

Flash application needed

Okay so today is tech support Monday.

So - I have over 20 mp3s of conference speakers and almost as many PPT presentations. I don't need to sync the power points with audio, but I would like to make them available in a Flash application (or possibly webexe).

Are there existing applications that will do what I'm looking for?
