UIScrollBar + Error #2007

[voxxsound]

The site I am working on has one main .swf and 4 other .swf subpages that I am loading into it. In the first subpage, I have a text box that I am loading dynamically, and I have also added a UIScrollBar component (all using AS). See below code:


var loadText:URLLoader = new URLLoader();
var loadReq:URLRequest = new URLRequest("assets/h_news3.txt");
var news_txt:TextField = new TextField();
var textScrollBar:UIScrollBar = new UIScrollBar();
var tf:TextFormat = new TextFormat();

tf.color = 0x666666;
tf.font="Franklin Gothic Book";
tf.size = 12;
tf.align = "justify";
tf.leftMargin = 7;
tf.rightMargin = 7;

news_txt.defaultTextFormat = tf;
news_txt.x = 313;
news_txt.y = 215;
news_txt.width = 425;
news_txt.height = 190;
news_txt.wordWrap = true;
news_txt.multiline = true;
addChild(news_txt);

textScrollBar.move(news_txt.x + news_txt.width, news_txt.y);
textScrollBar.height = news_txt.height;
textScrollBar.scrollTarget = news_txt;

loadText.addEventListener(Event.COMPLETE, textComplete);

loadText.load(loadReq);

function textComplete(event:Event):void
{
news_txt.htmlText = loadText.data;
addChild(textScrollBar);
loadText.removeEventListener(Event.COMPLETE, textComplete);
}



When I export this subpage, the scrollbar appears and works fine. When I load it into the main .swf, the scrollbar does *not* appear (even though you can click and drag where the scrollbar should be and it scrolls the text) and I get this error:

When I remove the code for the UIScrollBar it goes away, but something is happening between the 2 different .swf's and I cant figure out what it is. I have tried adding the TextField to the stage within the textComplete function, same with the UIScrollBar. Any ideas??

*Note: I did post this issue a few weeks ago but didnt get a response. Since it was part of another string and I didnt include the source code I thought I would try again. Any help here would be greatly appreciated. I have *got* to get this project done

The UIScrollBar is not finding the component skins in your library. Try adding the UIScrollBar to the library of you other Flash file.

That was it! Thank you! I was actually starting to feel like I moved out of the noob realm.. Guess not :p
