argument number error in learning AS3 Cookbook

[wusj]

I have a problem in Actionscript(Flex 2),Problems:1137: Incorrect number of arguments. Expected no more than 0 in line 6.Thanks,

package {
    import flash.display.Sprite;
    public class ExampleApplication extends Sprite
    {
        public function ExampleApplication(  ) {
         	var average:Number = average (1, 2, 5, 10, 8, 20);
        }
        private function average(  ):Number {
			var sum:Number = 0;
			
			// Loop through each of the elements of the arguments array, and 
			// add that value to sum.
			for (var i:int = 0; i < arguments.length; i++) {
			sum += arguments[i];
			}
			// Then divide by the total number of arguments
			return sum/arguments.length;
		}
    }
}

oh, you need the ...arguments in the params place. see here: http://www.senocular.com/flash/tutor...3withflashcs3/

// Using the ...(rest) parameter
function passAnything(...statements):void {
    trace(statements.length +": "+ statements);
}
passAnything(); // traces 0:
passAnything(1); // traces 1: 1
passAnything("a", true, 0); // traces 3: a,true,0 

I take it you are working out of the AS 3.0 cookbook judging by the name of your class. If so, how did you get the first couple of examples to work. (see my post here too).

I can't get the first couple of examples to work. Maybe it is just me, dunno.
