Tell us what’s happening:

Your code so far

function multiplyAll(arr) {
  var product = 2;
  // Only change code below this line
  for (var i = 0; i< arr.length; i++){ 
    for (var j = 0; j <arr[i].length; j++)
     console.log( product = product * [i][j]);
  } 
  // Only change code above this line
  return product;

}
// Modify values below to test your code
multiplyAll([[5,1],[0.2,4,0.5],[3,9]]);

You have [i][j] but you probably meant arr[i][j]. Also, why does product start at 2?

Yeah, just like @kevcomedia said, you forgot to type the array name before the index.
