Dynamic XML Image Slider auto scroll question

I Have a question regarding a dynamic XML driven image slide show.

I want the movie to slide continuessly from the left side automatically when it is loaded.
Now it only loads when a mouse movement enters the screen.

The link is:

Here is the code from the main time line, Frame 2 (Frame 1 loads the XML file:

stop();
// Number of items
itemNum = 15;
// Stage Dimentions
stageWidth = 700;
stageHeight = 300;
// Button’s width
width = 169;
// Separation between the buttons
separation = 20;
// Distance between the buttoms
space = width + separation;
// Total width of the buttons line
limit = itemNum * space;
// Speed
speed = 5;
for(i=0; i<itemNum; i++) {
_root.attachMovie(“mc_button”,“mc_button”+i,10+i);
ref = _root[“mc_button”+i];
// Vertical Positión (_y)
ref._y = stageHeight/5;
// Horizontal Positión (_x) + separation (20px)
ref._x = ( space * i ) + separation;
// Loads the picture description
ref.info.descName=picturesXML.firstChild.childNodes*.childNodes[0].firstChild.nodeValue
// unloads the marc
ref.marc.unloadMovie()
// Load the picture(.jpg)
ref.marc.loadMovie(picturesXML.firstChild.childNodes*.childNodes[1].firstChild.nodeValue)
// The link where will go when press
ref.link=picturesXML.firstChild.childNodes*.childNodes[2].firstChild.nodeValue
}
onMouseMove = function(){
movement = int(((_xmouse - (stageWidth/2))/-(stageWidth/2)) * speed);
}

And here is the code from the movie clip timeline (frame 1):

// picture scale
marc._xscale = marc._yscale = 100
// link
var link:String;
// Moving

onEnterFrame = function() {
// Adjust the position
this._x += _root.movement;
// if is outside the right limit…
if ( this._x > _root.limit - _root.width ){
// … goes to the left limit
this._x -= _root.limit;
}
// if is outside the left limit…
if( this._x < -_root.width ) {
// … goes to the right limit
this._x += _root.limit;
}
}
// Getting URL when press
info.onPress=function(){
getURL(“http://”+link)
}

Any help would be greatly appreciated.
Thanks,
