Medium Priority

Hi Experts

I have a windows application and a Crystal report on it. I use the running total to get a sum of money per group. And when I try to get the average of that running total it says: "This field cannot be summarized". Okthen I tried to do it manually: sum({@Consumption}) / {#Count} But then when I run the report it says: "Division by zero" Can you please help me on getting the average in a report?

Thanx in advance

A running total is calculated as the report is printed.  Summary functions are done much earlier in the report process.

Where did you put the Average formula?

What is #Count?

What is the formula for @Consumption?

1) I put the Average Formula in a Group Footer

2) #count is a running total set to 'Count' instead of 'Sum' to get the total amount of items to divide by

3) @Consumption = ({FuelRecords.Kilometers} - {FuelRecords.PrevKM}) / {FuelRecords.Fuel}

There isn't supposed to be a group with no records. But I tried your formula but I still get the error, Division by zero.

Thanx mlmcc for all your help, When I actually ran the program for the first time the error was much more descriptive and I could get the problem. So for anyone who just switches between views on your crystal report and get errors that don't explain anything, just run the program then the error will give you an exact description
