SUM data on 3 WEEK

[Luke_Killer_IT]

Hi, 

I would like to sum up the data from 3 weeks. I used such commands: sum ({<KW = {'$ (= Max (KW))'}>} MLA_MMT) but it does not work. HELP

HI,

I have one more question whether it is possible to create a new column that groups my data as shown in the screen

HI,

okay, I managed to come up with something like this, it's even cool, but you need to refine some ideas to improve it a little so that where there is zero, it does not enter the value in advance.
