.
What I would like to calculate is (AValue2-AValue1) for a given Num
(here num1).
In this case, I would have to calculate
60-50 for Num 10
and
43-55, 62-43 for Num 25.
Do you have any idea if it can be done simply with a request...
I thank you
Regards.
Alain Reymond

about the size of index ?
Any advise ? I thank you in advance.
