Remove onRollOver and have button automatically play

I have some code for a button, I'm trying to remove the onRollOver and onRollOut functions and have it automatically play the button effects.
What do I need to do to just have this automatically play?:confused:

Code:

---

//default size
sizeTo = 100;

//increase the size and play the effect animation when mouse is over the button
onRollOver = function(){
        effect.gotoAndPlay(2);
        sizeTo = 130;
}

//revert to 100% size when mouse cursor is out
onRollOut = function(){
        sizeTo = 100;
}

//dynamically adjust the size of the button
onEnterFrame = function(){
        caption._xscale = caption._yscale = caption._xscale+((sizeTo)-caption._xscale)/5;
}

Try using the onEnterFrame method.

since ur using a gotoAndPlay, onEnterFrame will make it act like a gotoAndStop, because it will be repeatedly going to that frame, just remove the functions all together, change

PHP Code:

---

onRollOver = function(){
    effect.gotoAndPlay(2);
    sizeTo = 130;
}

//revert to 100% size when mouse cursor is out
onRollOut = function(){
    sizeTo = 100;
}

to

PHP Code:

---

effect.gotoAndPlay(2);
sizeTo = 130;

if you want a way to change the size back, its going to have to be something other than rollOut, because you wont have a rollOver
