Selection Based on Categorized column

HiI got a view with the first column categorized, i’m trying to categorized the second column, based on the expanded value of the first column.

FORM is something like this –

has multiple sections with different values in each section

eg

BRIDGES

 Appraisals

 Design 

SOFTWARE

 cadd

 Visual Basic

 Word

DATABASE

 Oracle

 Access

(i’ve made list fields for each, section) and a list field for all sections

eg. Categories = Bridges:Database

 BridgeList = Appraisals

 DatabaseList = Oracle:Access

so i would like to see something like this in my view

Say UserA,

has in the Bridges SEction selected Appriasals

and Databse Section Selected Oracle and Access

and UserB

has in the Bridges section selected Design

has in the Software section selected Word

and in the Database section selected Access

this is what i would like to see

BRIDGES

appriasals

           UserA

Design

           userB

SOFTWARE

Word

           UserB

DATABASE

Oracle 

           UserA

Access

           UserA

           UserB

I dont’ know how else to explain it, so if you have any question, please ask,

and Thanks in advance to all
