Cannot summarize my calculated field(number)

Question

I am using Crystal Reports XI  version 11.5.3.417
My calculated field formula is:
IIF({bw_spread.fy_period}=totext(dateadd("m",3,{@max_data_date}),"yyyy.MM"),{bw_spread.actual_cost},0)
bw_spread.fy_period (string) and typical data = 2008.04
@max_data_date (datetime) and gets 3 months added, then turned into text in the same format as fy_period
bw_spread.actual_cost(number)
It takes a text field that has the Fiscal Period and compares it to the a Date that has been re-formatted as text, then returns the actual cost if they are equal else zero.
The formula works and returns a number and shows up nicely in the report.  The problem is, that I cannot SUM this field in the group footers.

This may not directly apply to your situation,  but here is something I found.
Create 3 formulas as below ;
Formula 1 :- RunningTotalName
WhilePrintingRecords;
CurrencyVar Amount;
Amount := Amount + {Customer.Last Year's Sales}
Place the above formula on the details section . and suppress this
formula if u dont want to display .
Formula2 :- Display
WhilePrintingRecords;
CurrencyVar Amount
Place this formula on PageFooter Section
formula3 :- AmountToReset
WhilePrintingRecords;
CurrencyVar Amount := 0;
place this formula on PageHeader section and suppress the same.
