I want the report to show: Name: NameField Surname: SurnameField Where the "NameField" and "SurnameField" are the fields returned by the StoredProcedure. The special requirement, is that if "SurnameField" is empty or null, then I don't want to show the "Surname: SurnameField". How can I achieve this?

问题 I have a Crystal Report 11 file that is a letter. The first Details section contains a large text box that has print date, address block, and the salutation line.
