// This line makes the button, btnCalculate wait for a mouse click
// When the button is clicked, the displayDebtBurden function is called
btnCalculate.addEventListener(MouseEvent.CLICK, displayDebtBurden);

// This is the displayDebtBurden function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function displayDebtBurden(e:MouseEvent):void
{
    // declare the constants
    const INITIAL:Number = 481.5;

    // declare the variables
    var year2007:Number;
    var year2008:Number;
    var year2009:Number;
    var year2010:Number;

    // calculate the debt burden per year
    year2008 = INITIAL * 0.97
    year2009 = year2008 * 0.97
    year2010 = year2009 * 0.97

    // put the values into the labels
    lblyear2007.text = INITIAL.toFixed(1);
    lblyear2008.text = year2008.toFixed(1);
    lblyear2009.text = year2009.toFixed(1);
    lblyear2010.text = year2010.toFixed(1);
