onPress calling a function - scope issue?

programming flash
1

I think this is a scope issue, but can’t be sure. I am using FlashDevelop, Actionscript 2.0 to create my movie. I call the sendAndLoad() function to display data from a database. I also have “Previous” and “Next” buttons to move through different data.

Since I was going to load data in three different locations (Load, Previous, Next) I created a LoadData() function. This function contains the sendAndLoad() to the server.

The initial load works great with the LoadData() function, the first record is displayed correctly. My problem is when I program the onPress for the Previous and Next buttons.

Why does my LoadData() function not run when inside the Previous/Next button onPress events?

Thanks,
Kris

example code:

class Main
{
private var parent:MovieClip;

public function LoadData()
{			
	var sVars2:LoadVars = new LoadVars();
	sVars2.cID = _global.ClientID;
	sVars2.tID = _global.cTicketID;
	
	var lVars2:LoadVars = new LoadVars();
	lVars2.onLoad = function(success) {
		if (success) {
			//success
		} else {
			//not successful
		}
	} 
	sVars2.sendAndLoad(url, lVars2, "POST");
}

function Main(mc:MovieClip)
{
	this.parent = mc;	

            //Buttons Created	
	
	_root["next"].onPress = function() {	
		this.LoadData();
	}	
	_root["prev"].onPress = function() {
		this.LoadData();
	}
	LoadData();
}


static function main(mc:MovieClip)
{
      var app = new Main(mc);		
}

}
