Nested movie

hi all
please help me complete this , i am trying to target a moive inside a movie to tween
this is the code
Code:
[LEFT]circles = [];for (i=0; i<4; ++i) { var mc = this[‘circle’+i]; mc.idx = i; circles* = mc; mc.onRollOver = function() { for (i=0; i<4; ++i) { if (i == this.idx) { var scale = 150; circles*.doTween(scale, circles*._x, 500); } } }; mc.onRollOut = function() { for (i=0; i<6; ++i) { circles*.doTween(100, circles*._x, 500); } };}[/LEFT]

this code is working very well , but i need to target inside the circle movie (cr+i) movie , every circle has a movie inside it, the tween should be applied for the nested movie
