mysql_tquery(g_iHandle, "SELECT * FROM `houses`", "House_Load", "d", playerid); 

then

add playerid to forward House_Load(); 
public House_Load().

Then change: House_Refresh(i); 
Into House_Refresh(playerid, i); 

After that:

House_Refresh(houseid) 

to House_Refresh(playerid, houseid)

Oh wait this above won't work because OnGameModeInit doens't have a playerid variable.
