Subreports and Login Information

[donv]

Hi all
I have been facing problems with subreports while executing a web report. I am passing oracle login information to the main report through hidden fields to the main report.The subreport is also prompting for logon information(login, password) and even after I supply the same, no data is appearing on the report.
I made a subreport link by selecting a field to link to the main report and I selected the same field as the subreport parameter field to use. Also the data sources for both the reports are different.I placed the subreport in the footer section of the main report. I request help/suggestions as soon as possible.

Thanks
Donv
