Hi,
I've made an script that ban players. It works fine but when i type 1 letter in reason, it will ban me.
Example: /ban 5 a

PHP код:

CMD:ban(playerid, params[])
{
    new
        targetid,
        Reason,
        AdminName[MAX_PLAYERS],
        TargetName[MAX_PLAYER_NAME],
        banmsg[128];
    if(PlayerInfo[pAdmin][playerid]>2)
    {
         if(sscanf(params, "is[50]", targetid, Reason)) return SendClientMessage(playerid, 0xE90A0AFF, "[CMD] /ban [playerid] [reason]");
        if(!IsPlayerConnected(targetid)) return SendClientMessage(playerid, 0xE90A0AFF, "[ERROR] Invalid player ID.");
        GetPlayerName(playerid, AdminName, sizeof(AdminName));
        GetPlayerName(targetid, TargetName, sizeof(TargetName));
        format(banmsg, sizeof(banmsg), "[ADMIN] Admin %s has banned %s [Reason: %s]", AdminName, TargetName, Reason);
        SendClientMessageToAll(0xE90A0AFF, banmsg);
        TextDrawShowForPlayer(targetid, Textdraw0);
        TextDrawShowForPlayer(targetid, Textdraw1);
        TextDrawShowForPlayer(targetid, Textdraw2);
        PlayerInfo[Banned][targetid] = 1;
        Kick(targetid);
    }
    else
    {
        SendClientMessage(playerid, 0xE90A0AFF, "[ERROR] You are not authorized.");
    }
    return 1;
} 


I have the same problem with /kick
What's wrong?
