Force reset sum in group line that aren't printed

How can I force a reset sum if the “Appearance Condition” result is "False” and the line group will not be printed. In the “Group Sums” it seems that only the selected sum variables are reset each time the group line is printed. I need to reset the sum variables in the group line that will not be printed too.
Thanks in advance.

One way is to write a very tiny group line (for example a font 1 pt height, white color).


In that way the line would be printed with blank values although with a tiny line. It’s the only way? Thanks.

The easiest that comes to my mind.

Keep in mind that empty lines are usually removed, so you need to use an empty, non-eraseable text (chr$(160)) with a 1 pt font, color white, in one field.
