totals without individual rows

Hi,

I like the simplicity of Creator but I have a problem, which I presume should be easy to solve: I want summary views which only report the sums of given numerical fields, when records are grouped. For example, I have a form called "transactions" that has a field "year", a numerical field "fees" and a field called "project". I just want to have a view showing the yearly totals, without the individual projects within one given year. By default, it seems that views report all individual rows...

How do you do that in Creator?

thanks,
Charles
