Using MC name from a loop to call up another MC

I’ve been searching and trying to figure this out for a while, but haven’t gotten it to work.

I have a bunch of buttons “b1” - “b12” which are set up in a “for” statement. Then on a rollover of each button, I want a popup to appear which I have created called “b(#)popup”. The way I have it set up, when I trace the variable “popup” I get “b(#)popup” like I want, but it is not causing the popup to appear. Does anyone know what my problem is here?

Thanks.

for(i = 1; i < 13; i++){
this[“b” + i].onRollOver = rollover;
this[“b” + i].onRollOut = rollout;
}

function rollover() {
this.gotoAndPlay(2);
var popup = (this._name + “popup”)
popup._visible = true;
trace(popup);
}
