Sorry for double post, I have a new problem. This is my code:

pawn Code:

zcmd(setrank, playerid, params[])
{
  new string[128];
    new idx;
    new tmp[256];
    new sendername[MAX_PLAYER_NAME];
    new giveplayername[MAX_PLAYER_NAME];
    
  if (AccountInfo[playerid][AdminLevel] >= 3 || IsPlayerAdmin(playerid))
    {
        tmp = strtok(params, idx);
        if(isnull(tmp))
        {
            SendClientMessage(playerid, COLOR_WHITE, "USAGE: /giverank [playername/id] [rank 1-8]");
            SendClientMessage(playerid, COLOR_WHITE, "FUNCTION: Will give selected player selective rank.");
            return 1;
        }
        new giveplayerid = ReturnUser(tmp, playerid);
        new rank = strval(tmp);
        if(giveplayerid != INVALID_PLAYER_ID)
        {
          if ((rank >= 1) && (rank <= 8))
          {
                GetPlayerName(giveplayerid, giveplayername, sizeof(giveplayername));
                GetPlayerName(playerid, sendername, sizeof(sendername));
                printf("ADMIN: %s gave %s rank %s.", sendername, giveplayername, RankNames[rank-1]);
                format(string, sizeof(string), "Admin %s has set your rank to %s.", sendername, RankNames[rank-1]);
                SendClientMessage(giveplayerid, COLOR_LIGHTBLUE, string);
                format(string, sizeof(string), "ADMIN: Administrator %s has given %s rank %s.", sendername,giveplayername,RankNames[rank-1]);
                SendClientMessageToAll(COLOR_LIGHTRED, string);
                AccountInfo[giveplayerid][Rank] = rank-1;
                format(string, sizeof(string), "You have given %s rank %s.", giveplayername,RankNames[AccountInfo[giveplayerid][Rank]]);
                SendClientMessage(playerid, COLOR_LIGHTBLUE, string);
            }
            else return SendClientMessage(playerid, COLOR_RED, "Invalid Rank!");
        }
    }
    else SendClientMessage(playerid, COLOR_GREY, "You are not authorized to use that command!");
    return 1;
}

It compiles fine and all, but when I use the command it always returns rank as 0. If I type /setrank 0 5 it would say "Invalid Rank".
