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

// This is the determineResult function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function determineResult(e:MouseEvent):void

{
    //Declare the variables
    var Depth:Number;
    var Counter:Number = 0;

    //Set the variables to the values
    Depth = 30

    //Introduce the while statement for calculating the time until topsoil is unsuitable for farming
    while (Depth >= 9.25)
    {
        Depth = (Depth - (Depth * 0.01)) + 0.005;
        lblResult.text  = "It will take " + Counter + " years for the soil to erode to a depth that crops will not grow ";
        Counter++;
    }
