Count, sum question?

I think this is easy but ...
Namely, I want to count recodrs in crystal report based on one field e.g. if table.field7=1 then count else do not count. Samething I want to do with sum function ( e.g sum only records where table.field5=0)
How to do that?

There are a couple of ways.

The easiest is to use "Running Totals", which have a variety of options for counting, summing etc. - including using formulas.

Create a formula, you can count sum anything you want using formulas.
