I just can't work out the variable here!

Question

Hi team,
I have some code that I am trying to put onto 10 different moviclips m1, m2 m3 etc to 10
I have tried to use every hint and bit of code that has been given to me by others here but I just can't get it to work..
I am trying
for (var i =1; i<=10; i++){
trace("m"+i);// this gives me the right result but doesnt work in the code..
I have tried
m[i]
["m"+i]
MovieClip("m"+i)
this.[m+i]
..... and heaps more!  I just can't get it to work.
Here is the code I am trying to use this variable on, 
Thanks for any help,
sub
m1.minX = 132;
m1.minY = 182;
m1.maxX = 930;
m1.maxY = 720;
// Initialize the circle at a random coordinate within the acceptable range.
m1.x = Math.random() *m1.maxX -m1.minX;
m1.y = Math.random() *m1.maxY -m1.minY;
// Set the velocity of the circle to six pixels/frame.
m1.vel = .003;
/* Initialize the x and y vectors for the circle clip. A "vector",
   in circle case, is a line that both direction (angle) and speed ("velocity").
   Here the direction is either horizontal (x-axis), in the
   case of "vx," or vertical (the y-axis), in the case of "vy."
   So, while it may appear that we're just assigning one number, the
   velocity, keep in mind that we've also determined the direction by
   distinguishing these values as either horizonal ("vx") or vertical ("vy").
   BUT -- while all that is true, it's also cheating a little (remember, this
   is the "simple" version.) The reality is that we're really using 2 speeds
   and 2 directions, where a vector is truly a single direction and single
   speed.  See the "complex" version for that execution.
m1.vx = Math.random() * 3;
m1.vy = Math.random() * 3;
// Define an onEnterFrame() method for the circle so that it continually updates
// its position.
m1.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
function enterFrameHandler(e:Event):void {
    // Calculate the new x and y coords for the circle clip on each frame
    // based on what happened in the previous frame (in the conditionals below.)
   m1.x +=m1.vx;
   m1.y +=m1.vy;
    // If the circle is touching the rectangle or is outside its boundaries,
    // change direction.
    if ((m1.x +m1.width/2) >=m1.maxX) {
       m1.x =m1.maxX -m1.width/2;
       m1.vx *= -1;
    else if ((m1.x -m1.width/2) <=m1.minX) {
       m1.x =m1.minX +m1.width/2;
       m1.vx *= -1;
    if ((m1.y  +m1.height/2) >=m1.maxY) {
       m1.y =m1.maxY -m1.height/2;
       m1.vy *= -1;
    else if ((m1.y -m1.height/2) <=m1.minY) {
       m1.y =m1.minY +m1.height/2;
       m1.vy *= -1;

The correct way to target instances m1 thru m10 using bracket notation would be... 
this["m"+i]
or even more correctly...
this["m"+String(i)]
