Help adding Buttons [ AS 2 ]

How do I add a like e.g get URL or load movie without losing animation

I added this to test but it stops the animation

but1.onRelease = function(){
getURL(“javascript:alert(‘you clicked me’)”);
};

// This Class is required from www.laco.wz //
#include “lmc_tween.as”
but1.bodyText = “Immigration Law”;
but2.bodyText = “Employment Law”;
but3.bodyText = “Property Law”;
but4.bodyText = “Family Law”;
but5.bodyText = “Corporate Law”;
but6.bodyText = “Commercial Law”;
but7.bodyText = “Oil & Gas Law”;
but8.bodyText = “Tenancy Law”;
but9.bodyText = “Criminal Law”;
but5.bodyText = “Contact Us”;

this is contained inside the button


// Set parameters here //
var rotateMax = 3
var effectSpeed = 0.5;
var offsetSpeed = 0.8;
var textXChange = 10;
var textBrightChange = -5;
// Code you can modify /
var textX = _parent.textBox._x;
var maxText = textX+textXChange;
var textBright = textBrightChange;
var boxMaxX = this._xscale;
var boxMinX = boxMaxX-5;
var boxMaxBright = 0;
var boxMinBright = -15;
var butSize = boxMaxX-30;
_parent.textBox._visible = false;
this._xscale = butSize;
this._alpha = 0;
this.tween("_xscale", boxMaxX, 3, “easeInOut”, 1);
this.alphaTo(100, 2, “easeIn”, 1, onEnd);
function onEnd() {
_parent.textBox._visible = true;
}
but.onRollOver = function() {
this.rotateTo(rotateMax, 2, “easeInOut”);
_parent.textBox.rotateTo(rotateMax, 2, “easeInOut”);
_parent.textBox.tween("_x", maxText, effectSpeed, “easeOut”);
_parent.textBox.brightnessTo(textBright, effectSpeed, “easeInOut”);
this.tween("_xscale", boxMinX, effectSpeed, “easeOut”);
this.brightnessTo(boxMinBright, effectSpeed, “easeInOut”);
};
but.onRollOut = function() {
this.rotateTo(0, 2, “easeOutElastic”);
_parent.textBox.rotateTo(0, 2, “easeInOut”);
_parent.textBox.brightnessTo(0, effectSpeed, “easeInOut”);
_parent.textBox.tween("_x", textX, effectSpeed, “easeOut”);
this.brightnessTo(boxMaxBright, effectSpeed, “easeInOut”);
this.tween("_xscale", boxMaxX, offsetSpeed, “easeOutElastic”);
