Turn off horizontal scrollBar

How would I go about turning off the horizontal scroll when pulling up a scroll component.

I tried to get a handle on the horizontal scroll policy but cant seem to get it.

her is what Im doing.

import fl.containers.ScrollPane;


var url:String = "rewards/gettingAroundR.swf";
var url2:String = "rewards/homeCoolingR.swf";
var url3:String = "rewards/homeHeatingR.swf";
var rewScrolHold:MovieClip = new MovieClip();
var rewclip1:Loader = new Loader();
var rewclip2:Loader = new Loader();
var rewclip3:Loader = new Loader();
rewclip1.contentLoaderInfo.addEventListener (Event.COMPLETE, completeHandler);
var myScrollPane:ScrollPane = new ScrollPane();
myScrollPane.source=rewScrolHold;
function completeHandler (e:Event)
{
    
    myScrollPane.setSize (635, 300);
    myScrollPane.move (0, 0);
    scrollHold.addChild (myScrollPane);
    myScrollPane.source=rewScrolHold;
    
}
rewclip1.load (new URLRequest(url));
rewclip2.load (new URLRequest(url2));
rewclip3.load (new URLRequest(url3));

rewScrolHold.addChild (rewclip1);
rewScrolHold.addChild (rewclip2);
rewScrolHold.addChild (rewclip3);
rewclip2.y = 304;
rewclip2.y = 304;
rewclip3.y = 824;

the content is less then the scroll size but the horizontal scrollBar is still showing. Thanks for any help

import fl.controls.ScrollPolicy;

myScrollPane.horizontalScrollPolicy = ScrollPolicy.OFF;

Good luck!
