Flash MX : Help with attaching & moving multiple mc's

Making a random motion “node Nav” where the square nodes attach by a line to another square.

I have the first one made and working good so now i need to add the others and I would like to do this without ‘onEnter’

i have:
this.attachMovie(“squareNode”, sNode, this.getNextHighestDepth());

i know i can attach as many as i want by looping:

this.attachMovie(“squareNode”, “sNode”+x, this.getNextHighestDepth());
x++

but I am stuck 'cause I cant access the movieclips ._x and ._y positions in the same manner (makes me think the method for attaching the movie is not the best route)

thx.
snx
