This is how I do it but it may be by no way the best way to do it.


Input a shared variable into your formulas for example:

Whileprintingrecords;
Shared numbervar total

If {string.name} = 'harry' Then
total:=Total + 1

basically that is a count, but you can do the same with any valuesSo instead of the +1 if it was a values you could say

If {string.name} = 'harry' Then
total:=Total + {Salary}; 'yes I know this is a currency, you should change your variable type to currencyvar'

Total;

--------

In another formula you can then call the variable

Whileprintingrecords;
Shared currencyvar total;
total;

hope this helps
