We have BeginDate and EndDate parameters which are DateTime fields and it prompts the user for these dates by looking at the OpenDate&Time field. When we go to the sub-report, we still have the same parameters but the date field is now a StartDate&Time field and it prompts us to enter these dates twice. We would like to have the client enter the date only once and be used in both date criteria. By the way, the Open & Start datetime fields are in different table views. . I'm new at Crystal Reports and have taught myself most of what I know. Can someone help me out? Thanks. Suzq2
