Question : Averaging a Sum in Crystal Reports

I have been working on a Crystal Reports report that shows the sales for associates.  It is one report with sales for two different years broken down by months.  I add up all the sales from Jan to Dec of a particular year and add the year's sales allocation number to get a final total for the year.   I got the final total for the year by doing a running total from Jan to Dec of the year.  Then I sum the Running total and the Year's sales allocation to get a final total for the year.  This formula works for both 2005 and 2006 years.  The problem I'm having is trying to average the 05 and 06 totals.  I can't seem to get the average of the two total numbers for both years because it's a formula.  

Here's an example:

Sally Salesperson
West Coast Territory
Year 2005
         Jan       1000
         Feb       4000
         Mar       3000
           .            .
           .            .
         Dec       9000

Running Total from Jan to Dec   //This formula is hidden in the report - This formula work for 2006 as well.
2005 Sales Allocation  12000
2005 Final Total      34000       //I create a formula that will use the Running Total and add the Sales Allocation number. Here is formula "@sum = {#RTotalFundSales}+{tblMonthly.Sales Alloc}"

Year 2006
         Jan       1000
         Feb       2000
         Mar       3000
           .            .
           .            .
         Dec       9000
Running Total from Jan to Dec       // This formula is hidden in the report
2006 Sales Allocation     34000     //This number is different from the 05 Sales Allocation)
2006 Final Total               75600     //The formula created for the 2005 Final total works for this final total because of the grouping.  

Two Year Average Final Totals for Sally Salesperson = In this example, the average of  05 Final Total (34000) and 06 Final Total (75600)  is 207800.  
//I've tried to write a formula to average both the 05 and 06 Final totals but it seems that I can't average a formula. I can't hard code the numbers because the report can be generated by salesperson.  So every salesperson will have a different outcome.

Any suggestions on how I can get the two Final totals to average would be greatly appreciated.

Answer : Averaging a Sum in Crystal Reports

How do you get that as the average?

Have you tried using the SUMMARY capability?

You might have to use a manual running total with variables.

In the report header
Add a formula
Name DeclVars
Formula
WhilePrintingRecords;
Global NumberVar MyTotal := 0;

In the detail section
Add a formula
Name DeclVars
Formula
WhilePrintingRecords;
Global NumberVar MyTotal;
MyTotal : MyTotal + {SaleField};

In the footer where you want to calculate the average
Add a formula
Name DispAverage
Formula
WhilePrintingRecords;
Global NumberVar MyTotal;
MyTotal / 2  ' Use whatever formula for the average.
