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; i <arr.lenght; i++){
    console.log(i)
    for(var j = 0; j<arr[i].lenght; j++)
    console.log(j)
    console.log(arr[i][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]]);
