Problem to calculate the days

[#1]

Hello i am new in Qlikview and i want do calculate the days (OPTTAG).

The Problem:

as you can see i try to calculate the OPTTAGE.

For example when i make a sum, then i should get for Bern Tisch 1 for the first Jan 0,5 and not 1,5.

I get the total form all the Fallnummern, but i dont need this.

below you see the script, i tell them if the SNZ is biger than 0.1562500000, then he should count 1 day, if the SNZ is lower than 0.1562500000 then count 0,5 days.

I need the SNZ for the OPSaal not for the Fallnumer.

What do i have to write, to get the sum for the OPSaal per day and not for the Fallnummer.

Please i need some help.
