Re: Having difficult time getting subtotals to work

Ah that helps.

Modify the formula on the Details section to:

whileprintingrecords;
numbervar pen;

numbervar gh1_sub;

if {prhpost.postcode} = '001' then
    pen := pen + {prhpost.amount};

    gh1_sub := gh1_sub + pen;

    pen;

Create a formula with this code and place it on the Group Footer 1 to display the total:

whileprintingrecords;
numbervar gh1_sub;

Create a reset formula with this code and place this on the Group Header 1:

whileprintingrecords;
numbervar gh1_sub := 0;
