Sound and Pausing Tutorial

Make sure you have this code:
this.onEnterFrame = function()
{
timer++;
.
.
.
if (Key.isDown(Key.SPACE))
{
i++;
if(timer >= 8)
{
_root.attachMovie(“Bullet”, “Bullet” + i, _root.getNextHighestDepth());
root[“Bullet” + i]._x = Ship.x + 3;
root[“Bullet” + i]._y = Ship.y;
timer = 0;
}
}
}
and this also:
if (Key.isDown(Key.SPACE))
{
i++;
if(timer >= 8)
{
_root.attachMovie(“Bullet”, “Bullet” + i, _root.getNextHighestDepth());
root[“Bullet” + i]._x = Ship.x + 3;
root[“Bullet” + i]._y = Ship.y;

var shoot_sound = new Sound();
shoot_sound.attachSound(“shoot”);
shoot_sound.start();

timer = 0;
}
}
