Hello i made one command to make houses it was working but i edited it more ands its better but now the code its crashing the server

pawn Код:

command(house, playerid, params[])
{
    new string[256];
    new query[256];
    new x_v[256];
    new idx;
    new intid,virtualworld,sale,sold;
    x_v = strtok(params, idx);

    if(!strlen(x_v))
    {
        SendClientMessage(playerid, COLOR_GREEN , " OPTIONS: create");
        return true;
    }
    if(strcmp(x_v,"create",true) == 0)
    {
        intid = 0;
        virtualworld = 0;
        sale = 1;
        sold = 0;
        new Float:XX,Float:YY,Float:ZZ;
        GetPlayerPos(playerid, XX, YY, ZZ);

        format(query, sizeof(query), "INSERT INTO houses (id,entrancex,entrancey,entrancez,Interior,VirtualWorld,ForSale,Sold) VALUES (NULL,%f,%f,%f,%f,%f,%f,%d,%d,%d,%d);",XX,YY,ZZ,intid,virtualworld,sale,sold);
        mysql_query(query);

        CreatePickup(1273, 19, XX, YY, ZZ);

        format(string, sizeof(string), " You have created one house at x: %f  y:%f  z:%f", XX,YY,ZZ);
        SendClientMessage(playerid,COLOR_GREEN,string);
    }
    return 1;
}

if someone type just /house it displays the send client messages but if i do /house create
it crashs my server. Where im i failing to happens this?
