Duplicated MC's and MC arrays.

I having two problems and I really don't know where to read up on to solve this.

This is my basic code:

var myclips = new Array("bill", "ted");
var sel = "MC"+n

for (i=0; i<myclips.length; i++) {
    t = this[myclips[i]];
    t.onPress = function() {
        _root.sel = this;
    };
}

MC.onPress = function() {
    startDrag(this);
    this.duplicateMovieClip(MC,"MC"+n,this.getNextHighestDepth(+1));
};

MC.onRelease = function() {
    stopDrag();
};


speed = 2;
speed2 = 10;
stop();

_root.sel._x += Key.isDown(76)*speed;
_root.sel._x -= Key.isDown(74)*speed;
_root.sel._y += Key.isDown(75)*speed;
_root.sel._y -= Key.isDown(73)*speed; 

And I also have a Next and Prev button that I can't seem to figure out how to code to get them to go forward and back from the myclip var.

So, basically, what I am trying to do is get a Next and Prev buttons to change the currant MC in the array, then once it's clicked, the sel var is selected and the MC is duplicated. From there, I am trying to get it to keep duplicating every time the original MC is clicked on.

Any help is good help.
