If statement stop an object from moving

I have a movie at this address
www.pjdcreative.com/rojo

I am trying the get the center movie to stop remaining centered with the scaling movie when It gets less than 200 pixels of the left hand margin. x.200 and stop being centered on the y axis also at 100 pixels y.100

Here is the current code I was trying to write that is positioned on the object: Just avoid the comments, just left them there for reference to what’s in my movie. Also need an if statement made for the y axis. (explained earlier)

onClipEvent(load){

this._x = Stage.width + 250; 
this._y = Stage.height/2;
// This function will Position the object in Place
// (The function is explained in the 'action' layer)
_parent.moveCenter();

	// This is alternate position if you dont want the easy tweening
	// so you can replace it with the above code.
	//this._x= Stage.width/2;
	//this._y= Stage.height/2;
	if (this.x < 200){
		this.x = 200
} 
	else if(this.x > 200){
	this._x= Stage.width/2;

}

Stage.addListener(this)
this.onResize=function(){
	_parent.moveCenter();
	//This is alternate position if you dont want the easy tweening>>
	//this._x = Math.floor(Stage.width/2);
	//this._y = Math.floor(Stage.height/2);
}

}
