Help in data report....!!!!

Hi all,
I am a newbie in vb and have been trying hard to prepare a data report. But the problem I am facing is that out of four grouped fields in the data environment I want only 1 field to be repeated and the rest should not repeat as per the requirement. The page header does not allow a textbox to be added. So I have to use group headers. When I add an extra group header to place the 3 fields on top that should not repeat on the group header above and the one field to be repeated in the bottom group header it gives an error "report sections do not match data source".

The fields are fileno., date, activity in group header above not to be repeated.

Expert Type in the group header below should be repeated along with the detail section.

Please tell me where I am going wrong and how can I correct this problem????????!!!!

Please help!!!!
Thanks in advance!!!!

The error message is elf explanatory. You'll have to change the hierarchy of command objects to reflect additional group in data report. They have to sync. If you require a group, sub-group and details in data report then data environment should also have command object for group, sub-group, and details.
