Rain With Splash

Alright, I am a total noob to AS so here is my problem:

I have some rain that falls and hits an instance of an MC called Pavement. I want it to create and MC called Splash (The name in the library).
Rain: (I already have the moving stuff thanks to a tut!)

 if (hitTest(_root.Pavement)) {
i ++;
duplicateMovieClip(_root.Splash,"Splash" + i,1);
this._alpha = 0;


 this._x = _root.Rain._x;
this._y = _root.Rain._y;

Thanks a ton,
