Max per Category doesn't work with NAMEOF

[gavexe]

I want to calculate a measure (_sellouts %) for different time periods (Day, week, month, year) selected by user.

It works almost fine:

But, as you can see Maximum value calculates wrong. 

If I get rid of selection and hardcode time period, the same code works well:

It seems as if Max per category doesn't work with NAMEOF() functions.

How can I get the maximum?

hello @gavexe as per my experience, you need to create a relationship between (_sellouts %) measure table and  the NAMEOF() table. Thank You.
