Database Report Summary Help

Hi All,

My first topic here and I hope I will be able to find a solution to my problem here.

I have a data table and I've created report from that table. Data table contains data for Area, Store and sales, cost and profit data on different column.

I have created a report that gives me data by Store and it works fine.

But I want to create a report that gives me summary by area. When I try to do that detail section repeats so many lines instead of giving me total for each area.
I mean if one of area contains 3 store than it's not showing me total of 3 stores instead it shows me 3 different line and 3 different figures instead of 1 in detail section.

Can any one please let me know how can I have summary?

Thanks.
