Hi I'm running into a problem here. I have a formula on my main report "if client.status in [100,200,300] then client.number". Then I link my client orderinfo subreport based on the formula. I have about 6000 clients with no order info but maybe only a handful with order info. It seems to run fine when I just put in those client numbers that I KNOW have order detail. I'm wondering if it's running into a problem because there are SO many without the order detail (and therefore the subreport returns nothing) that it doesn't like them combined for whatever reason in the same run.
