Problem with the console

I’ve been having this issue with some of the lessons and for the life of me i can’t figure out why.
sometimes the console doesn’t accept my answer even though i type the solution from hints word by word and i don’t really know why. but when i copy and paste the answer it works .


and here is the copied answer:

for (var i = 0; i < arr.length; i++) {
    for (var j = 0; j < arr[i].length; j++) {
      product = product * arr[i][j];
    }
  }

your screenshot and the code you posted do not match

oh tnx i guess i’m too tired
