How to adjust the frame number in this script?

Question

I have a timeline slider part to my animation which starts at frame 1089 and ends at frame 1173, I have a script which allows me to do this and works perfectly when I build it in a new flash file starting at frame 1, I need this code to work for the animation I have built at frame 1089, I dont know which number "1's" in the script relate to the frame number, I have tried changing them all to 1089 but that doesn't work! at the moment as soon as I click on this it jumps back to frame number 1 - which I believe as the code stands is exactly what it should be doing. Please could anyone edit this code so that it realises which frames I want it to work in?  Thank you in anticipation, Ellie x
var numOfFrames:Number = 84; // number of frames in the timeline to scrub
var widthOfScrubber:Number = 500; // width in pixels of scrubber bar
var widthOfScrubberSlider:Number = 25; // width in pixels of scrubber slider
var widthOfScrub:Number = widthOfScrubber - widthOfScrubberSlider;
var stepValue:Number = Math.round(widthOfScrub / numOfFrames);
var scrubX:Object = scrubber.scrubberSlider;
var isPlaying:Number = 1;
var home = this;
scrubX._x = 0;
onEnterFrame = function() {
if (scrubber.activeNow == 1 && isPlaying == 0) {
var frameNum = Math.round(scrubX._x / stepValue);
gotoAndStop(frameNum);
} else if (scrubber.activeNow == 1 && isPlaying == 1) {
var frameNum = Math.round(scrubX._x / stepValue);
gotoAndPlay(frameNum);
} else if (scrubX._x <= widthOfScrub && scrubber.activeNow != 1 && isPlaying == 1) {
scrubX._x = scrubX._x + stepValue;
} else {
isPlaying = 0;
playBTN.onRelease = function() {
scrubber.activeNow = 0;
isPlaying = 1;
home.play();
pauseBTN.onRelease = function() {
scrubber.activeNow = 0;
isPlaying = 0;
home.stop();

try:
var numOfFrames:Number = 84; // number of frames in the timeline to scrub
var widthOfScrubber:Number = 500; // width in pixels of scrubber bar
var widthOfScrubberSlider:Number = 25; // width in pixels of scrubber slider
var startFrame:Number = 1089
var widthOfScrub:Number = widthOfScrubber - widthOfScrubberSlider;
var stepValue:Number = Math.round(widthOfScrub / numOfFrames);
var scrubX:Object = scrubber.scrubberSlider;
var isPlaying:Number = 1;
var home = this;
scrubX._x = 0;
onEnterFrame = function() {
if (scrubber.activeNow == 1 && isPlaying == 0) {
var frameNum = startFrame-1+Math.round(scrubX._x / stepValue);
gotoAndStop(frameNum);
} else if (scrubber.activeNow == 1 && isPlaying == 1) {
var frameNum = Math.round(scrubX._x / stepValue);
gotoAndPlay(frameNum);
} else if (scrubX._x <= widthOfScrub && scrubber.activeNow != 1 && isPlaying == 1) {
scrubX._x = scrubX._x + stepValue;
} else {
isPlaying = 0;
playBTN.onRelease = function() {
scrubber.activeNow = 0;
isPlaying = 1;
home.play();
pauseBTN.onRelease = function() {
scrubber.activeNow = 0;
isPlaying = 0;
home.stop();
