Flexibreak / pagination at end of articles

Thanks for this lesson.
I understand a little bit more where are the files of Type and temlates.
But, i think my english is so bad because when i copy the code in item.php and item-html5.php, i display two table of content : i think one at the begining, the other one at the end ...

But it's not a table of content that i would like at the end of article. It's just pagination

I can put it at he begining but not at the end. This doesn't change ...

But like in modular.php i couldt not understand

Best regards
