Tree with choices : recursive scripts VS "Exit frame" action ?

Question

Hello,

I need some help !

I've build a multiple choices tree menu, which is quite
simple :

You start with, say, three entries : A,B,C

If you click A, it will "store" choice A and open "D,E,F,G"
and so on...

Each sub menu is actually a clip that appears in another
frame of its 
parent (DEFG is on frame 2 of ABC movie clip).

You can "unselect" any choice at any level and it should
unselect its 
children. And selecting a value unselects its brothers.

Everything was working OK until I had an extra constraint :
some 
children at the same level are not "exclusive" (that is you
can choose 
between "D or E" and "F or G" but they are still at the same
level and 
that's where my routine does not work any more...)

So I was thinking to "hard code" unselection, as I've got a
very little 
number of levels. That is, if a frame is left, it will erase
its 
possible choices.

Say, if I go back to "main movie - frame 1", its frame 2 will
call 
"delete D,E,F,G" on exit. And so would its nested clips if
they are open 
(visible on stage)

Any idea how to achieve this ? Some kind of "onExitFrame" ?

I don't post my recursive routine because it's been altered
so much I 
would spend to much time making it legible... Sorry..

Thanks in advance.

It works ! I cleaned up my recursive routine by passing an array of
"neighbours" to visit that I "pop" each time (and I discovered that you
have to use slice() to have a new array instead of a pointer !)

The main problem was in fact targeting neighbours that were not in the
same parent movie clip. And then came "targetPath(this)" that stored the
path for each button on root !

Hope this may help.
