hitTestObject movieclips FAILS

Hello everyone,

i am getting a trouble with the hitTestObject method.

I have three movie clips- p1_mc,p2_mc,ground_mc

lifea and lifeb are dynamic text boxes. They will record the life of players(it is a fighting game)

variables a & b will record which way the players are facing(left(0) , right(1))

But when i test the movie, hitTestobject only works on   condi(a boolean variable) and cond(a boolean variable)

*PS: this is a part of my whole actions code.

CODE:

import flash.events.*;

lifea.text='100'

lifeb.text='100'

var a = "1";

var b = "0";

MovieClip(root).addEventListener(Event.ENTER_FRAME,etf);

function etf(e:Event) {

          var condit = MovieClip(p2_mc.bk).hitTestObject(p1_mc.a_mc)

          if ( condit) {

                    if (b=="1") {

                              p2_mc.gotoAndStop(9);

                    }

                    if (b=="0") {

                              p2_mc.gotoAndStop(1);

                    }

                    lifea.text= String( Number(lifea.text)-10)

                    p1_mc.alpha -=  0.1;

          }

          var cond = (! p2_mc.hitTestObject(ground_mc))

          if ( cond ) {

                    p2_mc.y +=  3;

          } else {

                    k.p2up = false;

          }

          var condi = p1_mc.ak.hitTestObject(p2_mc.b_mc)

          if (condi) {

                    if (a=="1") {

                              p1_mc.gotoAndStop(1);

                    }

                    if (a=="0") {

                              p1_mc.gotoAndStop(9);

                    }

                    lifeb.text= String( Number(lifeb.text)-10)

                    p2_mc.alpha -=  0.1;

          }

          var co = (! p1_mc.hitTestObject(ground_mc))

          if (co) {

                    p1_mc.y +=  3;

          } else {

                    k.p1up = false;

          }

}
