Count Formula

[jasp]

Hi All, new to Rs, so any help would be appreciated.

I need to count the number of members withinin a  expression.

So if i have a formula say children ([2010]), it should give me all 12 months, what i would like to know is how many months have been counted.

I tried Count ([data item]) but it did not work , any help.

try

Code Select Expand

count(1 within set [data item])
It will create a 1 for each member in the data item set and count that. total(1 within set [data item]) will work just as well.
