Group Total Not working right

Hi,

I have a problem that i cannot figure out how to fix.

I have a sub report that i need to have the group totals in the Page header and i cannot for the life of me remember how to do this.

I have grouped by field 2 which gives me a time for Planned and unplanned events, I need to add up the time of the Planned items and put next to my Downtime Planned Text Box, and then sum the Unplanned and do the same against my unplanned downtime box

Regards SteveExample:
subreport 1 formula:
whileprintingrecords;
shared numbervar x:= sum({table.field})
subreport 2 formula:
whileprintingrecords;
shared numbervar y:= sum({table.field})
Formula in the main report:
whileprintingrecords;
shared numbervar x;
shared numbervar y;
x+y|||just to add some thing. You can use the sum function as

sum({table.field}, "Group on the field");

So you can get the planned and unplanned in the same subreport.|||Very confused with First reply, but will have a go at that, Second reply worked fine fo the same report

Regards

Steve
