Sub report

[roshnair]

i am using ms access 2003 & VBA .i have one main report and 3 sub reports embeddedd in the main report. if i am running teh subreport alone it is dispalying teh data.but if i am running teh main reoport all teh three subreports are not displaying any data? do i need to set anything programatically to dispaly it.and one more thing when i am running this main report it is asking for an unknown parameter .if i am cancellin g that pop up also main report is showing .how to avoid that?

Please let me kmow if anyone knows how to correct these 2 error.

Try running the query that the report is based on and see if the unknown parameter comes up.
The unknown parameter is something you've asked it to use in the query which it doesn't recognise.

What is the common link between the subreports and the main report.

Have you set master/child links or are you using filters.
