Crystal Reports/SQL Query Challenge

Need assistance with a specific logic problem in one of our Crystal Reports (v. 10). Report shows monthly revenue by invoice for the specified period with a comparison against the previous period. I'm trying to correct detail calculations and running totals to eliminate duplicate amounts caused by comparison against a period in which there was more than one invoice to a given customer. Having problems, since Crystal will not allow running total to reference a print-time formula. Looking for someone who can come up with workaround/alternate solution. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Report is a Crystal Reports version 10 .rpt file which uses and ODBC connection to a SQL 2000 stored procedure which handles the base query. I can email the .rpt file and SQL query to the person who will work on the project. Access to the database to refresh data, if required, will been through terminal services using an account we provide.
