Бан по нику

[DIMASIK]

Помогите сделать бан по нику.

if(strcmp(cmd, "/ban", true) == 0)
	{
	    if(IsPlayerConnected(playerid))
	    {
	    	tmp = strtok(cmdtext, idx);
			if(!strlen(tmp))
			{
				SendClientMessage(playerid, COLOR_GRAD2, "USAGE: /ban [playerid/PartOfName] [reason]");
				return 1;
			}
			giveplayerid = ReturnUser(tmp);
			if(PlayerInfo[playerid][pAdmin] >= 5)
			{
			    if(IsPlayerConnected(giveplayerid))
			    {
			        if(giveplayerid != INVALID_PLAYER_ID)
			        {
					    GetPlayerName(giveplayerid, giveplayer, sizeof(giveplayer));
						GetPlayerName(playerid, sendername, sizeof(sendername));
						new length = strlen(cmdtext);
						while ((idx < length) && (cmdtext[idx] <= ' '))
						{
							idx++;
						}
						new offset = idx;
						new result[64];
						while ((idx < length) && ((idx - offset) < (sizeof(result) - 1)))
						{
							result[idx - offset] = cmdtext[idx];
							idx++;
						}
						result[idx - offset] = EOS;
						if(!strlen(result))
						{
							SendClientMessage(playerid, COLOR_GRAD2, "USAGE: /ban [playerid/PartOfName] [reason]");
							return 1;
						}
						new year, month,day;
						getdate(year, month, day);
						format(string, sizeof(string), "AdmCmd: Игрок %s был забанен Администратором %s, причина: %s (%d-%d-%d-%d-%d)", giveplayer, sendername, (result),month,day,year);
						format(string, sizeof(string), "AdmCmd: Игрок %s был забанен Администратором %s, причина: %s,.", giveplayer, sendername, (result));
						SendClientMessageToAll(COLOR_LIGHTRED, string);
						format(string, sizeof(string), "Admin %s zabanil igroka %s . Realson : %s",sendername,giveplayer,result);
						BanLog(string);
						Ban(giveplayerid);
						return 1;
					}
				}//not connected
			}
			else
			{
				format(string, sizeof(string), "   %d не активный игрок.", giveplayerid);
				SendClientMessage(playerid, COLOR_GRAD1, string);
