I have created my own stats and put them in my hud, but when i mouseover there is no name for this Stat and not 3/10 or something like that, what must i do to treat them like a standard stat ?

I don't know - someone else reported this a while ago, but the Custom Stats I've created have all worked properly in the HUD.
Please Export your stat and attach it to a ticket on the Support system , and link to this thread in the reference field of the ticket so that we can investigate.

Look to the "fold to 3bet if raise first in" stat in the repository ! Thanks alot !

OK, I don't know why this is necessary, but you need to fill in the 'Format Summary Expression' too - the same string /%.2f will do.
