Topcount 10 showing less than 10

[Lisbeth]

Hi!
I have a cross tab showing eg revenue and order amount.
I have made a topcount (chains);10;tuple(revenue;current month). However, on some of my markets there's only 6 chains with revenue this month - and then I only want to show these 6 chains. But, I get the 6 chains plus 4 "extras" with no revenue on (they have an order amount, and therefore they do not get zero suppressed).
Can I set a property or something else on my topcount to solve this problem?
Thanx in advance ;)

filter(topcount (chains);10;tuple(revenue;current month),tuple(revenue;current month)<>0)

Thanks a lot - will begin using the filter function a lot!
