Summaries: Count, Sum etc. How?

Is there a quick and easy way to do a summary in Delphi 2.0 like you can in
Paradox. I can't find any info anywhere.

I could use a TQuery and set the SQL property accordingly but in this case
I want to sum a calculated field and Delphi doesn't seem to like this.

Any help would be very gratefully received. Thanks in advance.
