Cumulated results

Hi all,

I need to use one key figure that cumulated the results. So, I need to cumulated the sales results from January to the month selected.

My question is, I have a structure and in the selection I put the key figure "sales" and select the cumulated box in the characteristics, but the results are the same that if the key figure wasn't the cumulated box select.

What I need to do?

Thanks for the help.

Rita
