I am trying to make a button pulse when you rollover it and keep your mouse on it. I could use some help with te code below. I do understand what i am missing. The button grows when the mouse is over it and shrinks when you roll out but I would like it to pulse when on rollover. This is the code on the movieclip

onClipEvent(load) {  
// set initial scale to 100  
newscale = 100;  
}  
onClipEvent(enterFrame) {  
if (this.\_xscale \> newscale) {  
// shrink  
this.\_xscale -= 10;  
this.\_yscale -= 10;  
} else if (this.\_xscale \< newscale) {  
// grow  
this.\_xscale += 10;  
this.\_yscale += 10;

}  
}

and this is the code on the button inside the movieclip  
on (rollOver) {  
// set up for grow  
newscale = 150;

}  
on (rollOut) {  
// set up for shrink  
newscale = 100;  
}  
on (release) {  
// do something  
trace(“Home”);  
}
