calculate total from "DateDiff" number field

21 Views

Hi,

in my report, I've made a DateDiff formula to calculate the time between the beginning of the first event on a day and the end of the last event from the same day ;

this returns a number field.

When I try to summarize this field in order to have the total time per month, Crystal Reports returns the error message "impossible to summariz" ?

In my report, the data is grouped first by month and then by date.

Any idea's how to get this done ?

Thanks,

Marc
