Please help me out with conditional statements

Ok, I was wondering how you could use a button to control the random movement in the “CIRCULAR MOVEMENT” tutorial. It would be cool to see the movement stop and the image go back to it’s original position when you mouse over a button. I was thinking you could use an if/else statement but need help with the syntax. Any thoughts? Below is the code from the “CIRCULAR MOVEMENT” tutorial.

onClipEvent (load) {
var radius = 10 + Math.random() * 50;
var speed = 5 + Math.random() * 20;

var xcenter = this._x;

var ycenter = this._y;

var degree = 0;
var radian;

}
onClipEvent (enterFrame) {
degree += speed;
radian = (degree/180)*Math.PI;
this._x = xcenter+Math.cos(radian)*radius;
this._y = ycenter-Math.sin(radian)*radius;
}
