You can put this solution on YOUR website! .
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.
So, I think, something is FATALLY wrong with your post.
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.
