Need some easy (i think) help.

Yesterday i wrote this "for" loop to activate four buttons:

for (var i:int = 1; i<5; i++) {
this["button" + i].addEventListener(MouseEvent.MOUSE_OVER, overHandler);
this["button" + i].addEventListener(MouseEvent.MOUSE_OUT, outHandler);
this["button" + i].addEventListener(MouseEvent.CLICK, clickHandler);

Not i want to activate four more, but the are nested in another movieclip

my code looks like this now:

border.button5.addEventListener(MouseEvent.MOUSE_OVER, overBorderHandler);
border.button5.addEventListener(MouseEvent.MOUSE_OUT, outBorderHandler);
border.button5.addEventListener(MouseEvent.CLICK, clickBorderHandler);
border.button6.addEventListener(MouseEvent.MOUSE_OVER, overBorderHandler);
border.button6.addEventListener(MouseEvent.MOUSE_OUT, outBorderHandler);
border.button6.addEventListener(MouseEvent.CLICK, clickBorderHandler);
border.button7.addEventListener(MouseEvent.MOUSE_OVER, overBorderHandler);
border.button7.addEventListener(MouseEvent.MOUSE_OUT, outBorderHandler);
border.button7.addEventListener(MouseEvent.CLICK, clickBorderHandler);
border.button8.addEventListener(MouseEvent.MOUSE_OVER, overBorderHandler);
border.button8.addEventListener(MouseEvent.MOUSE_OUT, outBorderHandler);
border.button8.addEventListener(MouseEvent.CLICK, clickBorderHandler);

I dont know the how to write the code when the objects are nested in the "border" movieclip...

I have tried some variety.... like:

this["border.button" + i]....
or
border.this["button"+i]....

But it wont work, can someone please guide me in the right direction 😃
