i was wondering if there was a way to make this code work:

var button = mcMovie1;

on (rollOver) {  
button.gotoAndPlay(“two”);  
}

on (rollOut) {  
button.gotoAndPlay(“one”);  
}

where “button” would be recognized as “mcMovie1”, a movie instance. this way i can just copy and paste the same code over and over and not have to replace 5-10 movie instance names(whatevermovieclip.gotoAndPlay…) for all of them; instead replace one line: “var button = whatervermovieclip”
