emonCMS on PI3 local/ try to add results

Hi all,
I have installed the cms locally on a PI3. I try to log energy, oil heater and water consumption.
All sensor are working fine. My problem is to sum up the results on every feed. I added the inp+
process with the same arg. My expectation was an increasing output value but nothing happend.
How to realize?
Best regards
Uwe

Here are some screenshot of how I setup the feeds for water and kWh.
Hope it helps.


Thank You for the fast response. It works but it is postprocessing. Is there the possibility to add
in realtime? Can I speed up the processing?
What means the time value in the right raw?
Thanks in advance
Uwe
