Filter empty value

[AlexWest]

Hi colleagues, 

Please help with Filter codes.
I need to do a filter pane check:
If Filter is not chosen, show sum on Key pane.
I mean, I have filter with dates (years and days). 

And I have a Key pane with Clients sum.
And i can't make that if filter is not chosen, Key pane must show “-” symbol, or something like “chose a period”. 

Please help to realize the code.
Thanks a lot 🙂

and the filter data is Account_creation_date?

[AlexWest]

=[Account_creation_date.autoCalendar.Year]

is it critical? )))

[Bunim]

you most put in the getselectededcount() the same field that you put in filter.

I changed the value exactly like it is in the Filter's data, but nothing changed. The same message, that "Calculation conditions is not fullfilled."
