Not sure why [j] is not defined, would love some help!! Many thanks guys
**Your code so far**
function multiplyAll(arr) {
let product = 1;
// Only change code below this line
for (let i = 0; i < arr.length; i++){
for (let j = 0; j < arr.length[i]; j++){
}
product *= arr[i][j];
}
// Only change code above this line
return product;
}
multiplyAll([[1, 2], [3, 4], [5, 6, 7]]);

I would suggest formatting your code and it will help you see why you are getting that error message.
Right click in the editor and choose the format option
