Forum OpenACS Development: Problem in orderby of listbuilder - Help Me

Orderby expects values :::::

I've db_multirow which consists of mostly dynamically
build clauses and variables which comes from other forms
like

db_multirow ----lop---------- {

select ccc----------------------------]
where $clause2 and $clause1 and rrr = $other_form_value

} {
db_0or1row ll " "
}

My list builder builds out of "lop" mulitrow.
I included -orderby in list builder.
I want cc to be sorted in desc as well as asc.
But it doesnot work wen i click the da link of "ccc"
b'coz it expects the values that were used to build
the muiltirow.

So how do i pass variables from list builder to same
multirow out of which it is build or to same form itself.

I've tried few options like pass_properties {}
But remain unsuccesfull.

How do it ???
