OpenDayZ Rockstar!
Depends on what version you're talking about here guys. I haven't looked at the newest version of dayz mod.. but for the older version its simply a matter of following the instructions to the T. Especially the part about going through each one of the files and changing all "configfile" to "missionconfigFile." Then when adding items to the custom loot tables, make sure you are copying the syntax exactly.
