Tell us what’s happening:

Your code so far


function multiplyAll(arr) {
  var product = 1;
  // Only change code below this line
  for (var i = 0; 1 < arr.length; i++) {
    for (var j = 0; j < arr[i].length; j++) {
       product *= arr[i][j];
    }
  }
  // Only change code above this line
  return product;
}

// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);
