Which Epoch PBO do i use/edit? Help Please!

[Romefest66]

So I'm using the host HFB Servers to host my Dayz server, and when i try installing a script or etc into the epoch mission pbo; I cant figure out which one to edit/use.
In my mpmissions folder i have both DayZ_Epoch_11.Chernarus.pbo and DayZ_Epoch_17.Chernarus.pbo.
I'm using the chernarus map so i know its one of them but i cant figure out which one it is.
Are these the mission file(s) I'm even spose to be editing?
Any help will be greatly appreciated!

I hosted a dayz epoch server on the map chernarus asswell. I allways edited "DayZ_Epoch_11.Chernarus".
So i think thats the one you need
