Exporting Values from Subreport to Main report

[toblerone65]

Hello friends , I have a small question.
I have three paramters and I have subreport where I pass values to main report, I linked subreport to main report on those three paramters. I have grouping on amin report, I placed the subreport in grp footer 3a and in 3b below section i am showing shared varibales and other details, but when group chnages it valuea are not chaning, fore example I enter three paramters values 33455,4434,5345.
I did grouping on prameter fiels in both main report and subtrreport. Suppose for value 33455 sum of total $ is 50 and for 4434 sum is 65, but my shared variable is alwyas taking the last value i,e 65. I am doing anything wrong?,my subreport shared vaariable formula is like max(amount,po) so on. Please any help on this?.
Thanks a ton.
Toby.

Yes, you do get two, and I'm asking which one you are choosing. You should be choosing {?P01}, NOT {?pm-?P01}.

-LB

That is right LB I am choosing ?po1. But I m getting last value from the subreport.

You may want to look into using shared variables to do this.
I have made summaries in subreports which get passed back to the main report via a shared variable.

in the sub, in any formula (including formatting formula) add a line like so

@result
shared numbervar TotalCost := <summed val>

in the main report

@GTResultBuild
shared numbervar TotalCost;
global numbervar GTCost;
GTCost := GTCost + TotalCost;

//that lives in the next group footer down from the subreport so it always happens after the sub

@GTResultShow
shared numbervar TotalCost;
//this just prints it out
