Multiple collision detection problem

1

Hi all, I am trying to create a movie where several movieclips move towards the centre of the screen and organise themselves. I have the following code attached to the timeline, the clips move ok but dont interact. What am I doing wrong!?

target_mc  = ["mc0", "mc1", "mc2", "mc3"];
 

 movement  = function  () {   
     numMcs  =  target_mc.length;
     for (i=0; i<numMcs; i++) {  
         McA  =  target_mc*;
 

         for (j=i+1; j<numMcs; j++) {
             McB = target_mc[j];
             temp_A = eval(McA);
             temp_B = eval(McB);  
             var xpos:Number = temp_A._x;
             var ypos:Number = temp_A._y;
             if (xpos>200) {
                 temp_A._x = xpos - 10;
                 if  (temp_A, hitTest(temp_B))  {  
                     temp_A._x = xpos;
                 }
             };
             if (xpos<200) {
                 temp_A._x = xpos + 10;
                 if (temp_A, hitTest(temp_B))  {  
                     temp_A._x = xpos;
                  }
             };
             if (ypos<200) {
                 temp_A._y = ypos + 10;
                 if (temp_A, hitTest(temp_B))  {  
                     temp_A._y = ypos;
                  }
             };
             if (ypos>200) {
                 temp_A._y = ypos - 10;
                 if (temp_A, hitTest(temp_B))  {  
                     temp_A._y = ypos;
                 }
             }
         }
     }
 };
   
 this.onEnterFrame  = function()  {
 

 movement();
 

 };
