The buttons seem to work now. I found out that the cause of this error was because of my BMI variable. Now that the statement and BMI labels work most of the time, I just have a few questions.
1. How can I make make the BMI have two decimal places? I know you need .toFixed(2) but I do not know where to put it.
2. My statements appear to get cut off of when my test window is not enlarged. How can I make my whole statement fit in separate lines instead of the statement being in one long line?
3. How can I change the color of my BMI text label and Statement text label?
4. Sometimes my BMI and Statement labels won't appear somehow. Here are examples to visualize what I am talking about:
Working Metric: http://prntscr.com/fwiwzg
Working Imperial: http://prntscr.com/fwixk9
Nonworking Imperial: http://prntscr.com/fwixfy
Here is my revised code:
//import controls
import fl.controls.RadioButtonGroup;
import flash.events.MouseEvent;
import fl.controls.RadioButton;
// This line makes the button, btnDetermine wait for a mouse click
// When the button is clicked, the determineBMI function is called
btnDetermine.addEventListener(MouseEvent.CLICK, determineBMI);
// This is the determineBMI function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function determineBMI(e:MouseEvent):void
{
// declare the variables
var Weight:Number;
var Height:Number;
var MI:RadioButtonGroup = new RadioButtonGroup("MI");
// put the groups together
RadioMetric.group = MI;
RadioImperial.group = MI;
// get the number from the user
Weight = Number(txtinWeight.text);
Height = Number(txtinHeight.text);
// determine the BMI
