I think the sub report return happens in a data pass that occurs after the running total pass. You should be able to use it in a shared variable formula

not an evaluate formual but a shared variable formula. SOme peopel call the 'manual Running Totals'

is there a reason you have to use a sub report? I hate sub reports especially if you are having to run it for every detail row.

Hi

So I combined into 1 and still cant add the formula to the running to here is what i have:

Group1 is Client name
Group2 is service date

I but this formula in the G2 Header
WhilePrintingRecords;
NumberVar sum:=0;
sum := 0

I put this in Detail:
WhilePrintingRecords;
NumberVar sum;

sum := sum + if(cdate({RECORDED_SERVICE.STARTTIME}) in cdate({CLIENT_TREATMENT_HISTORY.ADMITDATE}) to cdate({@CHDischargeDAte})) then 1

I put this in GF2 :
WhilePrintingRecords;

NumberVar sum;

I think I have the order messed up?

The ultimate goal is
on GF2 (service date) I haveOne running total for each day of the month)  I look at the day of the month in the running total if "sum " = 0 then  I move an "X" to it if it is greater than 0 then I want blank
 
Then on GF1 (Client I display all 31 running total and it should have an X for each day that had a sum of zero

Thanks
