Nesting For Loops, Please Help!

Tell us what’s happening:
I’m not sure what I’m missing. Is it syntax? Am I missing something here?

Here’s the challenge criteria.
multiplyAll([[1],[2],[3]]) should return 6

multiplyAll([[1,2],[3,4],[5,6,7]]) should return 5040

multiplyAll([[5,1],[0.2, 4, 0.5],[3, 9]]) should return 54

Your code so far

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

// Modify values below to test your code

Link to the challenge:

take a look in your j loop initialization – arr[i].lenght is not actually the property name. Try arr[i].length instead…

Thank you so much! Good catch!
