first one is in writing everything in one line, that really sucks to read...
second one:
you are calling the GameTextForPlayer and the SendClientMessage function WITHIN the "format"...

pawn Код:

if(pInfo[killerid][pKills] == 10)
{
    pInfo[killerid][pRank] = 1;
    format(str,sizeof(str),""chat""OLD_ADMINCMD" [RANK] %s (%d) has been ranked up to rank {21DD00}'1'",PlayerName(killerid),killerid);
    GameTextForPlayer(killerid,"~r~Rank up",2500,1);
    SendClientMessageToAll(-1,str);
}
