Website Nav, Tween between pages in the same scene

programming flash
1

Hello, I am new to Actionscript and am working with AS3 in Flash CS3 to produce a portfolio website. Basically I have my flash set up with a 3x3 grid (9 boxes about 450px by 450px each box) and each box will have info and basically be a page that will be displayed in the masked area I have made.

I have already got the navigation working but I want to make it tween to each page with a deceleration effect. The following is my code for my navigation which currently works fine:

stop();

function goTopRight (e:MouseEvent):void{
gotoAndStop(3);
}
topright_btn.addEventListener(MouseEvent.CLICK, goTopRight);

function goTopMiddle (e:MouseEvent):void{
gotoAndStop(2);
}
topmiddle_btn.addEventListener(MouseEvent.CLICK, goTopMiddle);

function goTopLeft (e:MouseEvent):void{
gotoAndStop(1);
}
topleft_btn.addEventListener(MouseEvent.CLICK, goTopLeft);

function goCentreRight (e:MouseEvent):void{
gotoAndStop(6);
}
centreright_btn.addEventListener(MouseEvent.CLICK, goCentreRight);

function goCentreMiddle (e:MouseEvent):void{
gotoAndStop(5);
}
centremiddle_btn.addEventListener(MouseEvent.CLICK, goCentreMiddle);

function goCentreLeft (e:MouseEvent):void{
gotoAndStop(4);
}
centreleft_btn.addEventListener(MouseEvent.CLICK, goCentreLeft);

function goBottomRight (e:MouseEvent):void{
gotoAndStop(9);
}
bottomright_btn.addEventListener(MouseEvent.CLICK, goBottomRight);

function goBottomMiddle (e:MouseEvent):void{
gotoAndStop(8);
}
bottommiddle_btn.addEventListener(MouseEvent.CLICK, goBottomMiddle);

function goBottomLeft (e:MouseEvent):void{
gotoAndStop(7);
}
bottomleft_btn.addEventListener(MouseEvent.CLICK, goBottomLeft);

I have found another portfolio website that is almost identical to the one I want to make: http://www.dustontodd.com/

I would like to know how they have made the content tween smoothly and decelerate to each page and if possible be given a sample of the code and where to put it amongst the code I already have.

Thank you for your time :hugegrin:
