Please show the actual formula contents, not a paraphrase of it in the future, as you have led us astray here. If these are really summaries as you now indicate, then use a solution like FireGeek's (with some tweaks):
{@Reset} - put in higher order group header section that corresponds to the group level where you want the result, e.g., Group #1, and suppress:
WhilePrintingRecords;
NumberVar x := 0;
{@Accum} - put in GROUP #2 (or group section where your percentage formula is located) and suppress:
WhilePrintingRecords;
NumberVar x; //note this is NOT set to zero.
IF {@yourgroup#2summaryformula} > 0.2 THEN
x := x + 1;
{@Display} - put in footer section and show
WhilePrintingRecords;
NumberVar x;
"Total Count: " & ToText(x,0)
If you are confused about placement, you need to tell us what your group structure is, where your % formula is located, and at what group level you want the count.
