Trouble with a mouse trail

Hy. so i got one toutorial off the internet about mouse trail… but i cant seem to get it to work.

the toutorial lacks in documentation and it only sayd i should paste this script into my movie clip:

onClipEvent (mouseMove) {
i++;
this.duplicateMovieClip(“star”+i, i+10);
_root[“star”+i]._x = _root._xmouse;
_root[“star”+i]._y = _root._ymouse;
}
onClipEvent (enterFrame) {
if (this._name == “starParent”) {
_visible=0;
}else{
this._alpha -= 5;
this._rotation += 2;
this._xscale -= 5;
this._yscale -= 5;
if (this._alpha <= 5) {
removeMovieClip(this);
}
}
}


i pasted all of the text into frame 1 and made 2 movie clips one named “star” and another “starParent” but i get 3 errors that say:


Error Scene=Scene 1, layer=Layer 1, frame=1:Line 1: Clip events are permitted only for movie clip instances
onClipEvent (mouseMove) {

Error Scene=Scene 1, layer=Layer 1, frame=1:Line 7: Clip events are permitted only for movie clip instances
onClipEvent (enterFrame) {

Error Scene=Scene 1, layer=Layer 1, frame=1:Line 9: Type mismatch in assignment statement: found Number where Boolean is required.
_visible=0;

Total ActionScript Errors: 3 Reported Errors: 3
