In my project i create a grid of 100 squares dynamically through actionscript using something like:

\_root.createEmptyMovieClip(“allGrid”, 1);  
var newBox:MovieClip = allGrid.attachMovie(“box”, “box”+count, count);

so it names the 100 squares box1 to box100. when i roll over one of the squares, how do i tell which instance i am rolling over?

i.e.  
if inside the mc i put:

this.onRollOver = function(){}

how do i tell which instance “this” is?

well i want to use that information elsewhere in the program though, like show the coordinates in a textbox over on the side when i roll over a square.

how do i pass the name of that instance that i am in to somewhere else in the program?
