I need to calculate the sum of the group1 in crystal report.The report is like this.
Group1 is TypeID
Group2 is MemberID
Group2 has Details section.It has fields like Name,TransactionDate and Balance.

It looks as follows:
Group1Header TypeID
Group2Header MemberID
Details Name  Transactiondate   Balance    
           123        02/13/2011          $100  
           123        02/13/2011          $100
Group2Header MemberID
Details Name       Transactiondate   Balance    
                 345        02/13/2011        $200  
                 345        02/13/2011        $200
                 345        02/13/2011        $200
Group2Header MemberID
Details Name       Transactiondate   Balance    
                   ----         ---------                 ----
Group1Footer Sum for Group1 Sum(Balance)= $300

The sum has to consider only one record in each details section.Because the balance is repeating for the same member.
So, I need to consider it only once.
How to do this. Please let me know.

Thanks

Try this

Add a formula to the group 1 header
WhilePrintingRecords;
Global NumberVar grpTotal;
grpTotal := 0;
""

IN the group2 header add a formula
WhilePrintingRecords;
Global NumberVar grpTotal;
grpTotal := grpTotal  + {BalanceField};
""

In the group1 footer
WhilePrintingRecords;
Global NumberVar grpTotal;
grpTotal

You could also use a running total.  Right-click on the Balance field and select Insert > "Running Total".  Under Evaluate, select "On change of group" and select group 2.  Under Reset, select "On change of group" and select group 1.  Click OK to add the running total field and put it in your group 1 footer.
