Problem using Fractile with Set Analysis

[#1]

Hello,

I have created an expression using fractile that returns a value of 5% for physicians. When comparing all physicians, the correct value is returned. However, when I select one or more physicians from a list, my return value changes. Can anyone tell me what I need to add to my script so that the value stays static (meaning it will ignore any selections I make from a list of physicians.

fractile(aggr(count({<IBEX_DISPOSITION_ATN_NAME=, RETURN_QUALIFIER={'1'}>}IBEX_NUM) / (count({<IBEX_DISPOSITION_ATN_NAME=, RETURN_QUALIFIER={'1'}>}IBEX_NUM) + count({<IBEX_DISPOSITION_ATN_NAME=, RETURN_QUALIFIER={'0'}>}IBEX_NUM)),IBEX_DISPOSITION_ATN_LOGIN_ID),0.05)

Thanks!!

Scott
