Help making a treepage in htmldb- Carl/Scott please have a look

Question

How do I make a tree page of this data?
create table Flatfile
(Pgroup varchar2(30),
Pclass varchar2(30),
Manufacturer varchar2(30),
Article varchar2(30),
Price Number(6,2));
Insert into Flatfile Values
('Application Software','Database Software','Oracle','Oracle 10G',115);
Insert into Flatfile Values
('Application Software','Database Software','Microsoft','MS SQL Server 2000',200);
Insert into Flatfile Values
('Application Software','Spreadsheet Software','Microsoft','Excel',100);
Insert into Flatfile Values
('Monitor','15"','Acer','Acer 15"" TFT superscreen',199);
Insert into Flatfile Values
('Monitor','15"','Sony','Sony R1500 flat',225);
Insert into Flatfile Values
('Monitor','17"','Philips','Philips Flatscreen',250);
Insert into Flatfile Values
('Monitor','19"','Viewsonic','Viewsonic PLasma Monitor',275);
Insert into Flatfile Values
('Processor','AMD','AMD','FX-55',600);
Insert into Flatfile Values
('Processor','Intel','Intel','P4 3 GHZ',399);
I tried alot, but simply can't figure it out, please help:
A fixed level of two or three would be fine. I just don't understand the concept in creating one in htmldb. So:
Pgroup
---Pclass
Or
Pgroup
---Pclass
------Manufacturer
How must my query be written?
What do I fill in for these parameters:
Identify Query - You do not code the query. Instead, you identify the following:
ID - The primary key column of the table that is then used as the foreign key reference.
Parent ID - The foreign key column of the table that references the primary key column, thus forming the hierarchy.
Leaf Node Text - Select the column to display. Although this is a singular selection, you can edit the resulting query after it is defaulted to concatenate in other columns.
Link Option - If the tree is for informational purposes only, a Link Option is not necessary. If the tree will be used for navigation, select Existing Application Item.
Sincere,
Peter

Pete,
Your example begs the question - if it's too hard for you to navigate it, then it will DEFINITELY be too hard for your users.
Let's say I was looking for a Monitor on your site. I would have to search the entire top-level of the tree and come up with a list of several nodes which MAY contain what I'm looking for:
- LCD TV
- Monitors LCD
- Monitors CRT
- Plasma Displays
- Screens
- VGA
Instead, why not have a higher-level category called "Displays", then list each one of these sub-categories under it? Something like this:
+ Displays
  + CRT
    - VGA
  + LCD
    - Monitors
    - TVs
  + PlasmaI think that if you consolidate your tree, it will 1) solve your scrolling problem and 2) make your site more usable.
Thanks,
