Describe your issue in detail here.

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

}

multiplyAll([[1, 2], [3, 4], [5, 6, 7]]);
