Initialising an array of mcs variable problem

[sfpiano]

var str:String;
for(i=0; i<13; i++) {
	for(j=0; j<21; j++) {
		theScene["mask_"+i+"_"+j].onRollOver = function() {
			str = "mask_"+i+"_"+j;
			trace(str);
			theScene[str].gotoAndPlay(2);
		}	
	}
}

Everytime I run this it prints out mask_13_21, no matter which mask I'm actually on.

it's because that is the last known value of i and j. When you rollover any mc it will get the present value of 'i' and 'j' not what the value of i and j was when the onRollover event handler was defined for it. What u need to do is create a dynamic property for the movieclip at the time its onRollover handler is being defined e.g

var str:String;
for(i=0; i<13; i++) {
	for(j=0; j<21; j++) {

                theScene["mask_"+i+"_"+j].i = i;
                theScene["mask_"+i+"_"+j].j = j;
		theScene["mask_"+i+"_"+j].onRollOver = function() {
			str = "mask_"+this.i+"_"+this.j;
			trace(str);
			theScene[str].gotoAndPlay(2);
		}	
	}
}

or just

var str:String;
for(i=0; i<13; i++) {
	for(j=0; j<21; j++) {

		theScene["mask_"+i+"_"+j].onRollOver = function() {
			this.gotoAndPlay(2);
		}	
	}
}

The first one was to illustrate the point
