Convert as 1.0 to as 2.0

[matheussousuke]

When I place this code inside a as 2.0 fla, it doesnt work well, so it must be 1.0, right?

How can I convert (Flash 5) it to 2.0 (flash 8)?

n++;
if (n < 150) {
	duplicateMovieClip("nutz", "nutz" + n, n);
}
setProperty("nutz", _rotation, getProperty (nutz,_rotation) - n / .5);
tellTarget ("nutz") {
	gotoAndPlay(1);
}
