Manipulating MC on Main stage from external file

programming flash
1

I’m working on a small project where I have an external AS class which is passed the stage via the constructor. I then want to start/stop a movieclip on the main stage from that external class. Right now I’m getting an error stating that it’s not a property of the stage. Any help/enhancements would be greatly appreciated.

import aotRSS

//var url:String = root.loaderInfo.parameters.url // To be used later after testing
var url:String = 'http://www.domain.org/rss.php?limit=10'

var rss:aotRSS = new aotRSS(url, this.stage)
rss.updateData()
var feedUpdater:Timer = new flash.utils.Timer(1000*60*10)
feedUpdater.addEventListener(TimerEvent.TIMER, rss.updateData)
feedUpdater.start()

entryTitle.htmlText = rss.getTitle()
entrySummary.htmlText = rss.getDescription()

function periodicUpdate() {
	rss.rotateItems()
	entryTitle.htmlText = rss.getTitle()
	entrySummary.htmlText = rss.getDescription()
}

aotRSS.as
