Recursive function yields undefined

Hello happy people,

I have this function that I want to summarize number given from an array. If the out put total exceeds the variable maxSum I want the function to run again until it gets an result equals or lower than the maxSum.

Now when I test this I “undefined” as out put when the recursion is triggered. Below is my example code to test from. I hope that someone could help me solve this and hopefully explain what I’ve done wrong …


var myTimes:Number = 3;
var maxSum:Number = 20
var myArray:Array = new Array(6,5,6,9,8,6,6,8,6,9,5,7,8,5,6,8,7,9,7,5,5,8,5,7,5,5,5);

function calcSum(times:Number, array:Array) {
    var outPut:Number = 0;
    var sumarize:Number = 0;
    for (var i:Number = 0; i<times; i++) {
        sumarize = array[random(array.length)];
        outPut += sumarize;
    }
    //Check so that the outPut isn't greater then the maxSum
    if (outPut > maxSum || outPut == undefined) {
        calcSum(random(myTimes)+1, array);
    } else {
        return outPut;
    }
}

my_btn.onRelease = function () {
    trace(calcSum(myTimes, myArray));
}

kind regards, Ollu
