[Rocky Balboa]

look i tried to increase the player's score by 3 when he types a command and i got an error..btw i use kills[playerid] to save the kills and i put this on player spawn setplayerscore(playerid,kills[playerid]); and i tried to do this to increase the sscore by 5 , kills[playerid] + 5; but it gave me a worning which is : warning 215: expression has no effect. Now i tried to do that the other way , like this .. SetPlayerScore(playerid, GetPlayerScore(playerid)+5);
But the score didnt increase, now what should i do ? i could use kills[playerid]++ but that increase it by 1, i didnt want it to be by one .. any suggestions ?
