As your post is worded, it seems to me, from the context, that the second line should present
the recorded numbers - but it is empty, instead.

Please look on how it looks like at the forum - and compare with your source.

If you will find that corrections are needed, then make them and re-post your message to the forum.

Please do not post your updates to me in person.
