XML and Scrollbar Issues... Help please!

Hello. I’m having difficulties getting my scrollbar to drag properly when I dynamically load text from an XML file. Basically, the scrollbar and the text appears, the up and down buttons on the scrollbar work fine, but you can’t drag it. Here’s the code, it’s going to be part of a website to showcase a coin collection:

scroll1._visible = (box1_txt.maxscroll > 1);

var myCoins:XML = new XML ();
myCoins.ignoreWhite = true;
myCoins.onLoad = function (success)
{
var numcoins:Number = this.firstChild.childNodes.length;
arrHolder = new Array ();
for (i = 0; i < numcoins; i++) {
titleHolder = this.firstChild.childNodes*;
arrHolder* = titleHolder;
}
};
myCoins.load (“coins.xml”);

onEnterFrame = function (){
box1_txt.text = arrHolder[0].attributes.description;
scroll1._visible = (box1_txt.maxscroll > 1);
}

PS - I’m not too sure if onEnterFrame is the right thing to use here. I guess it shows I’m kind of a newbie. But any help you can offer will be greatly appreciated.

Thanks in advance
