[help! as2] how to access movie clips' _y inside a movie clip

programming flash
1

i got a school flash project where i need to access the _y properties of many movie clips buttons that set with name like sel 1 sel2 sel 3 and so on

the problem is i have 2 sets of those, one on the main timeline which i can access with “for” looped _root[“sel”+i]._y and one which is inside another movieclip

problem is i don’t know how to access the later using for loop :frowning: can someone help me with that?

this is the script that i used to access the _y on the _root.selx

for (i=1; i<numberOfButtons+1; i++) {
  if ((mySelection == i)&&(this._y != _root["sel"+i]._y)) {
    this._y = _root["sel"+i]._y;
  }
 }

anyone can help? please :nerd: :nerd: begging:nerd: :nerd:
