I tried doing in the script, but it is failing. for example first i want to find the Result time which is Max (Startdate) - Min(Enddate)
which i want to store in the new field result field, but qv says Expression error.
second Thing is i want to find the average result for each product per day. avg(Resultday)
The first one I have achieved in the frontend using a TextBox, but the second one I am unable to get it.
