If I remember correctly version 6.0 has two functions called storevar and fetchvar. You will need to use the storevar function in the subreport i.e. StoreNumberVar total := {Field.Name}; and then in the primary report you will need to init the varialable name in the RH  i.e. Numbervar total = ({field.name},0). Finally you will need to create a formula to display the value into the desired section i.e. FetchNumberVar Total + {theother.fieldname}. I have not included the exact syntax but this should get you started. NOTE: In version 8.5 all you would have to do is use a function called Shared Numbervar and this will do the same thing. If you plan to upgrade to the recent version of Crystal you will need to do some clean up on the report. This is because Crystal by default does Crystal Decsions is not supporting the StoreVar and Fetchvar functions. I hope this helps
