Hi Friends,
I have 2 listboxes: Study and Site.
I want only those sites to be shown under the selected study.
So i added the following expression to the site listbox :
aggr(only({<site_num= P(site_num)>}site_num),site_num)
It worked.
But 3 charts have to shown at study level and 5 on site level. So i created a 'study' alter nate state for the 3 charts and the study listbox. but now the site listbox is not getting affected by study listbox, as it is under inherited state(and so are the other 5 charts).
Can there be an expression for site listbox where it only picks up value of selected study from study loistbox, and not be a part of study alternate state?.
Thanks in advance.
