Scroll Back on XML News Feed???

[designchemist]

I can scroll forward to the next title and link, but is there a way to have a button to scroll back?

This is my code:

trace(_root.newsItems.length);

if (Number(_root.newsItems.length) == 0) {
	//This allows us to wait until our arrays have been initilised properly!
	gotoAndPlay(2);
} else {
	
	//Pick a random news item to display.		
	newsCount = random(_root.newsItems.length);
	
	//Check to make sure that the old news item is not the same as the current one. 
	if (newsCount == oldCount) {
		if (newsCount == _root.newsItems.length - 1) {
			//If the last element has been repeated, we should choose the first one. 
			newsCount = 0;
		} else {
			//Just go to the next news Item. 
			newsCount++;
		}
	}
	
	
	//Get the newsitem that has been randomly choosen
	nextNewsItem = _root.newsItems[newsCount]
	
	trace("newsCount: " + newsCount + " DisplayName: " + nextNewsItem.DisplayName + " URL: " + nextNewsItem.URL);
	
	//NewsLine is the text that the user sees.
	NewsLine = nextNewsItem.DisplayName;
	//Hit Url is the URL that the user will be sent to when they click on the hitButton
	//Which is the invisible top layer
	hitURL = nextNewsItem.URL;
	//Old Count is a way of keeping track of the last items and is used to 
	//Check that we don't get repeats in our code. 
	oldCount = newsCount;
}

Thanks a lot!

will:
newsCount--;
work?

You will need to check that newsCount isn't zero to begin with, but that should do the trick.
