How do I add a list of numbers stored in an array

Question

How do I add a list of numbers stored in an array? The code I
have is showing ‘NaN’ when I try to add the second item
in each element of the array:
var aItemPrices:Array = new Array(["item1_mc", 10], ["item
2_mc", 20], ["item 3_mc", 30]);
var totalPrice:Number;
for (i=0; i<aItemPrices.length; i++) {
//the following line traces 'NaN'
totalPrice += aItemPrices
[1];
trace("totalPrice: "+ totalPrice);

Answer 1

i modified your code in 2 places, check it
var aItemPrices:Array = new Array(["item1_mc", 10], ["item
2_mc", 20], ["item 3_mc", 30]);
var totalPrice:Number=0; //Mani changes
for (i=0; i<aItemPrices.length; i++) {
//the following line traces 'NaN'
totalPrice += aItemPrices
[1];//Mani changes
trace("totalPrice: "+ totalPrice);
