How to hitTest Within an Array?

[Coooooookies]

Okay so I have this thing where orbs are supposed to stick together, so I put them all in an array, and told them to stick together when they encounter another member of that array. However, they only stick in groups of up to four, and then the orbs begin to overlap and such. Any clue how to fix this, or am I not being clear enough? Thanks!

Can you define "overlapping"? Are the initial four not overlapping? Your existing code would also be very helpful.

Well... they're supposed to stay a certain distance apart from each other, as in if they're far away enough, they get close, but if they're too close, they get farther. They aren't supposed to overlap, but they do anyways. Before I paste my code, I have two more questions... any idea why my clump of orbs has an affinity for moving towards the -x and -y directions? I can't quite figure it out. And the second, is there a way to trace how many MCs an MC is hitting at one point? Thanks again

Orb Class:

class Orb extends MovieClip
{
    var xvisc; var yvisc;
    var xspeed; var yspeed;
    var momentum;
    var stability;
    var drag:Boolean;
    var size;
    var ratio;
    var base;
    var center;
    var maxspeed
    
    function onLoad()
    {
        xvisc = yvisc = 50;
        xspeed = yspeed = 0;
        momentum = 0.01;
        stability = .5;
        _root.circle.orbs.push(this);
        drag = false;
        size = _width = _height = 50;
        ratio = 2;
        base = _root.attachMovie("OrbBase", "OrbBase" + _root.circle.i, _root.circle.i - 500);
        base._x = _x; base._y = _y;
        center = _root.attachMovie("OrbCenter", "OrbCenter" + _root.circle.i, _root.circle.i + 100);
        center._x = _x; center._y = _y;
        maxspeed = 1
    }
    
    function onEnterFrame()
    {
        _x += xspeed;_y += yspeed;
        if(drag == false)
        {
            if(xspeed > maxspeed){xspeed = maxspeed;}
            if(yspeed > maxspeed){yspeed = maxspeed;}
        }
        
        base._x = _x; base._y = _y;
        base._width = base._height = _width + 10;
        center._x = _x; center._y = _y;
        
        for(var i in _root.circle.orbs)
        {
            if(this.hitTest(_root.circle.orbs[i]))
            {
                var distance = Math.sqrt(Math.pow(_root.circle.orbs[i]._x - _x, 2) + Math.pow(_root.circle.orbs[i]._y - _y, 2));
                
                if(_x > _root.circle.orbs[i]._x){xspeed -= (distance - (size/ratio))/xvisc;}
                if(_x < _root.circle.orbs[i]._x){xspeed += (distance - (size/ratio))/xvisc;}
                if(_y > _root.circle.orbs[i]._y){yspeed -= (distance - (size/ratio))/yvisc;}
                if(_y < _root.circle.orbs[i]._y){yspeed += (distance - (size/ratio))/yvisc;}
                
                if(distance < size/ratio + (stability * 5) && distance > size/ratio - (stability * 5))
                {xspeed -= 0.01; yspeed -= 0.01;}
            }
            else
            {
                if(xspeed > 0){xspeed -= momentum;} if(yspeed > 0){yspeed -= momentum;}
                if(xspeed < 0){xspeed += momentum;} if(yspeed < 0){yspeed += momentum;}
                if(Math.abs(xspeed) < momentum){xspeed = 0;}
                if(Math.abs(yspeed) < momentum){yspeed = 0;}
            }
        }
        
        if(xspeed < stability && xspeed < 0){xspeed += 0.01;} if(xspeed > stability && xspeed > 0){xspeed -= 0.01;}
        if(yspeed < stability && yspeed < 0){yspeed += 0.01;} if(yspeed > stability && yspeed > 0){yspeed -= 0.01;}
        
        if(Key.isDown(Key.CONTROL))
        {
            this.onPress = function()
            {drag = true;}
        }
        if(!Key.isDown(Key.CONTROL)){drag = false;}
        if(drag == true)
        {
            _x += (_root._xmouse - _x)/10;
            _y += (_root._ymouse - _y)/10;
            
        }
        
    }
    
}

And the Circle Class I used to attach and push the orbs:

class Circle extends MovieClip
{
    var orbs;
    var orblimit; var i;
    
    function onLoad()
    {
        orbs = [];
        orblimit = 10; i = 0;
    }
    
    function onEnterFrame()
    {
        this.onPress = function()
        {
            if(!Key.isDown(Key.CONTROL))
            {
                i++; if(i > orblimit){i = 0;}
                var neworb = _root.attachMovie("Orb", "Orb" + i, i);
                neworb._x = _root._xmouse; neworb._y = _root._ymouse;
            }
        }
    }
    
}
