Hello Xiaoxin Sheng,


The way I want it to work is as follows:

- With the slicer a date range is selected. For example, 01-01-2017 through 31-12-2017.

- I now want the average per group from the scores with a FIRSTDATE within this date range and the average per group from the scores with a LASTDATE within this date range.

- If an ID has multiple scores on the same FIRSTDATE or LASTDATE that should first be averaged before the group average is calculated.


The problem is that while a date range is selected with the slicer, for some ID's a date is selected which falls out of this range. As seen in my previous post, a date is shown from 2015. This is not correct, and the average is miscalculated because of that.


Is this more clear?


Kind regards.
