I am modifying an existing report in Crystal 8.5 with that provides a summary of procedures, patients, and minutes by period, quarter, and YTD. Each period represents one month of data with period one being July. When I run the report for period one, the data is correct. When I change my selection to period two, the period data is 0 and the quarter and YTD data is the same as it was for period one. There is also a graph that is supposed to represent the period data but it disappears when i change the period from period one. I have tried everything I can think of to make this work. I found one formula that does not show up on the report but simply has "Now" on it. What is this formula for? Any help will be appreciated!
