I have managed to get as far as creating running totals on a quarterly basis for my report in Crystal.  What I want to do now is obtain the product of these 4 totals?

For example, I have 1.05, 1.06, 1.07 and 1.08...I want a field that calculates them like so

1.05 * 1.06 * 1.07 * 1.08 = 1.286...

The totals were obtained after grouping the data using the Top N function in Crystal...

Any help would be greatly appreciated, as I'm brand new to Crystal and quite frustrated...

Thanks
Nick
