Flipping Book Component zoom in page question

Question

Hello,
I have a flipping book component that works well. It has also a zoom button and function that also works but too well. It zooms too much.
I would like to have it zoom in less, but I cant find out how to adjust the zoom percent.
Can anyone help with this? Here is the "START ZOOM Function" code...
// Zooming settings
zooming = false;
zoom_panel_mc.zoom_btn.onPress = startZoomingMode;
myBook.onClick = bookClick;
function startZoomingMode() {
myBook.flipOnClickProp = false;
myBook.autoFlipProp = 0;
showZoomPointer();
zooming = true;
function bookClick(pageNumber, page_mc, isCornerClick) {
if (!zooming) {
return;
var page_url = page_mc.URL;
if (page_url != undefined) {
open_popup(page_url, pageNumber);
} else {
zooming = false;
myBook.flipOnClickProp = true;
myBook.autoFlipProp = 50;
hideZoomPointer();
function open_popup(page_url, pageNumber) {
if (zoom_win != undefined) {
return;
hideZoomPointer();
zoom_win = mx.managers.PopUpManager.createPopUp(_root, Window, true, {title:"Page Number: " + pageNumber, closeButton:true});
zoom_win.createObject("ScrollPane", "zoom_pane", 0, {contentPath:page_url, _x:3, _y:31});
zoom_win.setSize(popup_width, popup_height);
zoom_win.zoom_pane.setSize(popup_width-6, popup_height-31);
listenerObject = new Object();
listenerObject.click = closeWindow;
zoom_win.addEventListener("click", listenerObject);
zoom_win._x = Stage.width/2-popup_width/2;
zoom_win._y = Stage.height/2-popup_height/2;
function closeWindow(eventObject:Object) {
zoom_win.deletePopUp();
zooming = false;
delete zoom_win;
myBook.flipOnClickProp = true;
myBook.autoFlipProp = 50;
function showZoomPointer() {
Mouse.hide();
attachMovie("ZoomIcon", "zoom_icon_mc", 0);
zoom_icon_mc.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
function hideZoomPointer() {
Mouse.show();
delete zoom_icon_mc.onEnterFrame;
zoom_icon_mc.removeMovieClip();

The lack of formatting (indentations) makes that much code very difficult to both read and follow logically, and with the amount of it, I decided it was better for you to try to find it than me after a quick glance failed to locate it.  That said... the function was just a line away from the line that prompted me to want to see it...
zoom_panel_mc.zoom_btn.onPress = startZoomingMode;  // this is why I wanted to see it
myBook.onClick = bookClick;
function startZoomingMode() {             // this is where it is hiding
myBook.flipOnClickProp = false;
myBook.autoFlipProp = 0;
showZoomPointer();
zooming = true;
