I have a report already written, and I want to filter the underlying query to get certain reccords, instead of writing a whole new one. I tried it once, and had to redo the whole report, it wouldn't open after I removed the filter on the query. I supposedly am supposed to be able to do this, but is there anything special that I need to do that isn't totally obvious? It is a large and complicated report, would that make a difference? Any help would be greatly appreciated. =)
