hi, I want to throw the {CommonValue_<name>} of the main table to the sub report. But when I try to open the sub report, {CommonValue_<name>} it will show NULL. How can I do this? Thank you very much.

When you use 'View and Check SQL', if the Common Value has no value, it will use NULL, so it may cause an error (depending on the SQL and your database engine).
The error may not occur if the user executes the report with a value.
So you may specify a default value to make the 'View and Check SQL' work.

OK,Thanks.If I want to throw the {CommonValue_<name>}(selected by the dropdownlist) from the main report(not main table) to the sub report. Can I do it?If I put the default value in the sub report, it may be different from the value in the main report dropdownlist.
