Auto scroll Gallery AS3 CODE

Hello!

Hopefully maybe someone can  help me with this. I have created a gallery with scroll buttons that works perfectly. However, I would like to have this auto scroll (maybe 2 seconds on each image) and I am not sure how to do this. My guess is I am completely over complicating it. I would love a second pair of eyes to give me an idea how I can achieve this.

Thank you so much for your help in advance.

AS3 CODE

stop();

Arrows.LA.addEventListener(MouseEvent.CLICK, backFrame);

Arrows.RA.addEventListener(MouseEvent.CLICK, forwardFrame);

import fl.transitions.Tween;

import fl.transitions.easing.*;

var nFrame:Number=1;

//ARROW FUNCTIONS

function backFrame(evt:MouseEvent):void

{

    if(nFrame>1) {

        nFrame--;

    } else {

        nFrame=5

    }

    Arrows.gotoAndStop(nFrame);

    var nX:Number=0-((nFrame-1)*379)

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, nX, .5, true);       

}

function forwardFrame(evt:MouseEvent):void

{

    if(nFrame<5) {

        nFrame++;

    } else {

        nFrame=1;

    }

    Arrows.gotoAndStop(nFrame);

    var nX:Number=0-((nFrame-1)*379)

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, nX, .5, true);

}

//FRAME BUILD FUNCTIONS

function frameA(evt:MouseEvent):void

{

    nFrame=1;

    Arrows.gotoAndStop(1);

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, 0, .5, true);

}

function frameB(evt:MouseEvent):void

{

    nFrame=2;

    Arrows.gotoAndStop(2);

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, 0, .5, true);

}

function frameC(evt:MouseEvent):void

{

    nFrame=3;

    Arrows.gotoAndStop(3);

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, 0, .5, true);

}

function frameD(evt:MouseEvent):void

{

    nFrame=4;

    Arrows.gotoAndStop(4);

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, 0, .5, true);

}

function frameE(evt:MouseEvent):void

{

    nFrame=5;

    Arrows.gotoAndStop(5);

    var myTween:Tween = new Tween(Gallery, "x", Strong.easeOut, Gallery.x, 0, .5, true);

}

Best,
