unlinking one listbox from rest of the listboxes

[#1]

i have used one of the listbox(LB01) as a heading(which is just an expression). now i want that when i select values from other listbox(LB01),  the heading, which is just a value in LB01 should not be highlighted. How can i do that?

chech this set analysis expression to ignore the selection.. under your help section..

sum( {1} Sales )
returns total sales within the application, disregarding the selection but not the dimension. If used in a chart with e.g. Products as dimension, each product will get a different value.

sum( {1<Region= {US} >} Sales )
returns the sales for region US disregarding the current selection.

My Expression is:

if(time_bckt_Nm= 'current month' and time_bckt_type= 'current', date(MonthEnd(CAL_DT), 'DD-MMM-YYYY'))

How to use set-analysis now in this expression?

I don't want them to be highlighted because, it has only one value and i have used that as a heading. So, it looks bad that if i select some values in the some other listbox, so this heading(which is a value in a listbox) also gets highlighted.
