Using a variable to change a variable

Question

Hey Everyone,
Here's the situation. I'm creating a board game which has 3
variables, p1Move, p2Move and activePlayer.
p1Move and p2Move store the p1 and p2 location on a game
board. activePlayer stored who's turn it is at the moment.
I am loading a value in from a text file which changes the
value of move. This all works fine when i designate a player
directly:
p1Move = [insert variable name],
but i want to designate dynamically based on who's turn it
is.
Something like this:
_root["p"+activePlayer+"Move"] += Number(this.varAmount);
so that flash changes the value of p1Move (or p2Move
depending on who's turn it is) to varAmount. varAmount is the
variable being read from the textfile.
Hopefully that all makes sense. Basically i want flash to
change the variable associated with the active player only.
Any help would be greatly appreciated, LB

well as the docs say above, if you 're-declare' those
variables that it will 'replace' the _global instance, so i still
don't think i'd go that route.
now above you say the the 'activePlayer' var works 'some' of
the time - but that the var is sent from a text file. I think that
you might try to load the variable from the file under a different
name, and the declare the named var in the root, for instance in
the text file use something like:
playerActive=1;
then in the root timeline where you load use something like:
loadVariables('file.txt');
activePlayer = playerActive;
however it's likely that this wont be consistent either
because the file has to 'load' before the variable is instantiated
(available) so I'd suggest using the LoadVars class to monitor the
load and respond when it becomes available. something like:
var lv = new LoadVars();
lv.onLoad = function() {
activePlayer = this.playerActive;
lv.load('file.txt');
