new cityhallpropertyoffice;
cityhallpropertyoffice = CreatePickup(1239, 2, 362.8641, 155.2817, 1024.7963, -1);

public OnPlayerPickUpPickup(playerid, pickupid)
{
	if(pickupid == cityhallpropertyoffice)
	{
	    ShowPlayerDialog(playerid, 6, DIALOG_STYLE_LIST, "Property Office", "Faction\nHouses", "Select","Close");
	}
	if(pickupid == accjob)

	if(dialogid == 6)
	{
	    if(response)
	    {
	        if(listitem == 0)
	        {
	            ShowPlayerDialog(playerid, 7, DIALOG_STYLE_LIST, "Bussines","Building faction","Buy","Close");
			}
			if(listitem == 1)
			{
			    ShowPlayerDialog(playerid, 8, DIALOG_STYLE_LIST, "Houses", "House 1\nHouse 2\nHouse 3", "Buy","Close");
			}
		}
	}

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
	if(dialogid == 7)
	{
		if(response)
		{
			if(listitem == 0)
			{
				new INI:File = INI_Open(UserPath(playerid));
				new name[MAX_PLAYER_NAME];
		 		GetPlayerName(playerid, name, sizeof(name));
  				INI_ParseFile(UserPath(playerid), "LoadUser_%s", .bExtra = true, .extra = playerid);
   				if(Chars[playerid][pBusiness] == 0)
				{
			    	INI_SetTag(File,"data");
			    	INI_WriteInt(File,"Business",Chars[playerid][pBusiness] = 1);
			    	INI_Close(File);
					Bfaction[playerid][Owner] = 1;
					pInfo[playerid] [pBuilding] = 1;

				}
				else
				{
					if(pInfo[playerid][pBuilding] == 1)
					{
						SendClientMessage(playerid,COLOR_RED,"This faction is allready bought from someone else");
					}
				}
			}
		}
	}
	if(dialogid == 8)
	{
	    if(response)
	    {
	        if(listitem == 0)
	        {
	            SendClientMessage(playerid,COLOR_RED, "There is no house for sale");
			}
 	        if(listitem == 1)
	        {
	            SendClientMessage(playerid,COLOR_RED, "There is no house for sale");
			}
 	        if(listitem == 2)
	        {
	            SendClientMessage(playerid,COLOR_RED, "There is no house for sale");
			}
		}
	}
    return 1;
}
