assistance with sql/sql reporting services 2000 (maybe just a sql issue)

This sql gives me the correct result and the report runs fine in Reporting Services. But the issue is that when i run the report against TEST database it gives errors like 'NaN' and 'Infinity'.. I know it is because some of the records in TEST are empty and so the calculation doesn;t take place for those records. So all i need is something like 'Is Null' expression in either the main query so that whenever their are nulls it gives '$0.00' Inseatd of 'NaN' and 'Infinity. I have attached the main query, the expression i am using to calculate and the screenshot of errors. Let me know if anything else is required to complete this task. I believe this won;t take more than 2 hours to figure out the correct 'IS NULL' expression. The only demand is that i need this one pretty soon. ## 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.
