Multiplication of variables

1

Hi there!

Here is the whole script of a test document which doesn’t work…
Excuse me but I never used multiplication of variables and I confess how shameful I feel.
I absolutely don’t understand the explanations the Flash Help contains…

Document contains three Input Fields, a Dynamic Field and a Button.
Clicking the Button returns NaN !!!

I thank you in advance for any help.

Best regards from Old Gerry

var a:Number = new Number(field1.text);
var b:Number = new Number(field2.text);
var c:Number = new Number(field3.text);
operationFct = function () {
	var res:Number = new Number();
	res = (a * b) + c;
	resultFld.text = res;
};
myButton.onRelease = function() {
	operationFct();
};
stop();
