Basic JavaScript: Nesting For Loops HELP!

Tell us what’s happening:

i’ve just done this exercise but i don’t actually know what’s missing, as i can’t pass neither one point.

Your code so far

function multiplyAll(arr) {
var product = 1;
// Only change code below this line

 for(var i = 0; i < arr.lenght; i++) {
    for (var j = 0; j < arr[i].lenght; j++) {
      product *= arr[i][j];
// Only change code above this line
return product;

var product = multiplyAll([[1,2],[3,4],[5,6,7]]);
