Do you use Y_INI?
if so

PHP код:

//I Rather use those.
PlayerInfo[playerid][pDeath] = PlayerInfo[playerid][pDeath]+1;
PlayerInfo[killerid][pKills] = PlayerInfo[killerid][pKills]+1;
//OR, as in default.
PlayerInfo[killerid][pKills]++;
PlayerInfo[playerid][pDeaths]++; 


EDIT: You know, changing values in general..

PHP код:

PlayerInfo[playerid][pDeaths] =0; //SETS IT TO 0.
PlayerInfo[playerid][pDeath] = PlayerInfo[playerid][pDeath]-1; //Minus 1. If 10, it's gonna be 9 


Like that
