pawn Код:

format(string, sizeof(string), "%s(%s): %s", GetPlayerName(playerid), GetPlayerID(playerid), text);

The players ID is an integer, not a string, try this:

pawn Код:

new playername[MAX_PLAYER_NAME], string[128];
GetPlayerName(playerid,playername,sizeof(playername));
format(string, sizeof(string), "%s(%i): %s", playername, playerid, text);
SendClientMessageToAll(COLOR_WHITE,string);

- Theres no need for GetPlayerID, since 'playerid' is exactly the same.
- GetPlayerName doesn't work like you did, but I fixed it for you.
