Hello

I'm having problems with VB DataReport.
I set a recordset that contains several fields including the "red squared" in the picture below:



When I'm trying to show this datareport I receive an error:"Report sections do not match data source".
I double-checked the fields and names, and the only thing that causes it is the Group Header. When I remove it everything works fine.
The problem is: I need to calculate and show rows from the record set grouped by one field.
I need to show all the rows in that specific group and calculate sum for 2 fields for each group.

Where did I go wrong?

Thank you.
