Default looping

hi all and thanks for the support till now, i hope you all guys had a nice vacation.

here is the problem:

i have a table with the following columns:

PID, PName, PPID, Level. P: Property, PPID: ParentpropertyId

now i have the following properties:

human level 1
 man level 2 subcategories
 woman level 2 subcategories
Animals level 1
 cats level 2 subcategories
 dogs level 2 subcategories
plants

the question is that i want to dispaly them like this: property first and then subcategories according to the relative property, for that i create the following queries:

to display the property:

select PName from tblproperty where level = 1

to display the subcategories:

select PNAme from tblproperty where level = 2 and parentpropertyid <> propertyid

in this second query i'm getting all the subcategories.

i created also this 2 for loops:

for i = 0 to counter1
  show property
   for j = 0 to counter2
      show subcategories
    next
next

now i'm getting for everyone all the subcategories even for the ones that did not have subcategories like plants

the output i'm getting now is:

human level 1
 man level 2 subcategories
 woman level 2 subcategories
 cats level 2 subcategories
 dogs level 2 subcategories
Animals level 1
 man level 2 subcategories
 woman level 2 subcategories
 cats level 2 subcategories
 dogs level 2 subcategories
plants
 man level 2 subcategories
 woman level 2 subcategories
 cats level 2 subcategories
 dogs level 2 subcategories

any idea how i can solve this problem?
do i need to change my query or add something to my loop
the parent propertyid is just a column to link the subcategory to propert, so human has PID = 1 level 1 , then man has parentpropertyid = 1 and level = 2

thanks

In your Parent Query Add PID field also like this -

select PID,PName from tblproperty where level = 1

And in the Parent Loop use a variable to store value of PID. And in Inner Loop use this query -

select PNAme from tblproperty where parentpropertyid=variable_name_that_holds_parent_q ueries_PID_Value
