Dear All,

I have Crystal Reports developed in Version 7.0. These reports are operating on Data Push model where I am pushing the dataset to the Crystal Report. 

In VB application, Crystal Design component is being used to view the reports. I am using CrystalReportViewer control to view the Crystal Report.

Some rpeorts are working fine. I am able to assign the dataset for all the reports along with its sub-reports. There are some reports, which have some sub-reports, and which expect some parameters. Morover, these reports are grouped on some database fields.

Such reports are throwing an exception:
"Invalid Group Condition"

Can anyone help me out in reoslving this problem.

Any idea or opinion is invited in this regard.

Thanks a lot, Brian.

I think this would have helped me a lot.

Further i got to know that this error was triggered by one of the groups used in a sub-report.

I tried by eliminating this group and hurray!!......Report shows up!!
