Snowfall 3.0

so i am editing the snow3.0 tutorial
here is my code

init = function () {
width = 970;
// pixels
height = 110;

w0 = 120;
w1 = 100;
w2 = 65;
w3 = 40;
w4 = 20;

l0 = 40;
l1 = 60;
l2 = 80;
l3 = 60;
l4 = 40;

// pixels
max_snowsize = 7;
// pixels
snowflakes = Math.random()5;
// quantity
for (i=0; i<snowflakes; i++) {
t = attachMovie(“leaf”, “leaf”+i, i);
t._alpha = 20+Math.random()60;
t._x = width-this[“w”+i];
t._y = height-this[“l”+i];
t._xscale = t._yscale=50+Math.random()
(max_snowsize
10);
t.k = 1+Math.random()2;
t.wind = -1.5+Math.random()
(1.4*3);
t.onEnterFrame = mover;
}
};
mover = function() {
snowflakes = Math.random(5);
}
init();

now it does everything i want it to do, but it doesn’t removed my movieclips when they have played out and doesn’t add anymore new movieclips?

any suggestion?

thanks!
