filtering

[#1]

Hello

I need to filter based on three types and each type has a set of criteria

type1= table1.value in(a,b) AND table2.value in(..) AND table3.value in(..)

type2=(table1.value in(c) AND table2.value in(1,2)) OR (table1.value in(c) AND table2.value in(3))

type3=type1 just different values

I would like to show just each type only in a listbox for the user.

Any ideas?

Thank you.
