Yes. That will happen as what your code does is that if the houseid is not found, It will break the loop. For example, if houseid 0 doesn't exists and 1 exists, It will stop the loop at 0. Try this

PHP код:

if(dialogid == NAVIDIALOGHAUS)
    {
        if(response)
        {
            for(new i=0; i<sizeof(hausInfo); i++)
            {
                if(!IsNumeric(inputtext))return SendClientMessage(playerid, COLOR_RED, "Du kannst nur Zahlen eingeben.");
                if(strval(inputtext) == hausInfo[i][hausnummer])
                {
                    SetPlayerCheckpoint(playerid, hausInfo[i][hx], hausInfo[i][hy], hausInfo[i][hz], 5);
                    SendClientMessage(playerid, COLOR_WHITE, "Das Haus wurde auf der Karte markiert.");    
                    return 1;
                }
            }

            return SendClientMessage(playerid, COLOR_RED, "Die Hausnummer gibt es nicht.");
        }
        else
        {
            return 1;
        }
    }
