Store instance name of btn pressed in variable?

1

okay… im creating 100 movie clips through duplicate movie and assigning each MC an instance name of eh_1, eh_2, eh_3 etc… on rollover i would like to have have them store in a variable which button number they are.

to detect rollovers and presses, im just using

for (i=1; i<101; i++) {
_root["eh_"+i].onRollOver = function () {
};
}

is there anyway i can detect which button was pressed and store into a variable the number?

thanks
