Creating a Sum using a running total and a conditional formual

I need to clasify if a case has more than one request associated with it.  I was able to accomplish this through groups and a running total.  The data looks like this

Group a
Request 1
Request 2
   Running total 2

Group B
Request 1
    Running total 1

Group C
Request 1
request 2
Request 3
   Running total 3

Now I want to determine how many cases (groups) have more than one associated request.  I created an if/ then formula based on the running total, but I can't sum this as already includes summary data.  From looking at other posts, I think that I need a variable, but I am unsure how to do this and what forumla(s) I might need.  

I just want a total sum of all cases (groups) that have more than 1 request associated with it.  Any help will be greatly appreciated.

Try this

In the report header create a formula
WhilePrintingRecords;
Global NumberVar MoreThan1Count;
""

In the group footer
WhilePrintingRecords;
Global NumberVar MoreThan1Count;
If {#RunningTotal} > 1 then
     MoreThan1Count := MoreThan1Count + 1;
""

In the report footer
WhilePrintingRecords;
Global NumberVar MoreThan1Count;
MoreThan1Count

If you need the total number of cases just add another variable and calculate as you go.

Thank you, that worked perfectly.  Do you know of any resources, on this website or others, that explains variables and how to use them?
