Select values in table with button

[#1]

Hi.

I would like to create a button where I could select values that are 1 or 0 from a pivot table.

I have tried with action Select possible and type =if(sum(Check_Done) <= 1),Placecheck_Station).

Is there any one that a solution for this?

Use set analysis to create the rule:

Sum({$<Check_Done = {1}>} Placecheck_Station)

will give you the 1 values

That doesn't work. I have attached an example.
