My report is in the following way, I built a report of person, then in the report head, I have the basic person inforation, such as name, address. and then i add a sub report which is about the education of this person, and another subreport is about Career. I use personid in every report database. but I can not know how to use subreport. when i preview the print, i can not see any record in subreport.
Thank you.
